-== Code of Conduct
-
-This project is governed by the https://github.com/spring-projects/.github/blob/main/CODE_OF_CONDUCT.md[Spring code of conduct].
-By participating you are expected to uphold this code.
-Please report unacceptable behavior to spring-code-of-conduct@pivotal.io.
-
-[[how-to-contribute]]
-== How to Contribute
-
-[[ask-questions]]
-=== Ask Questions
-
-If you have a question, check Stack Overflow using
-https://stackoverflow.com/questions/tagged/spring-security+or+spring-ldap+or+spring-authorization-server+or+spring-session?tab=Newest[this list of tags].
-Find an existing discussion, or start a new one if necessary.
-
-If you believe there is an issue, search through https://github.com/spring-projects/spring-security/issues[existing issues] trying a  few different ways to find discussions, past or current, that are related to the issue.
-Reading those discussions helps you to learn about the issue, and helps us to make a decision.
-
-[[find-an-issue]]
-=== Find an Existing Issue
-
-There are many issues in Spring Security with the labels https://github.com/spring-projects/spring-security/issues?q=is%3Aissue+is%3Aopen+label%3A%22status%3A+ideal-for-contribution%22[`ideal-for-contribution`] or https://github.com/spring-projects/spring-security/issues?q=is%3Aissue+is%3Aopen+label%3A%22status%3A+first-timers-only%22[`first-timers-only`] that are a great way to contribute to a discussion or <<submit-a-pull-request,to a PR>>.
-You can volunteer by commenting on these tickets, and we will assign them to you.
-
-[[create-an-issue]]
-=== Create an Issue
-
-Reporting an issue or making a feature request is a great way to contribute.
-Your feedback and the conversations that result from it provide a continuous flow of ideas.
-However, before creating a ticket, please take the time to <<ask-questions,ask and research>> first.
-
-If you create an issue after a discussion on Stack Overflow, please provide a description in the issue instead of simply referring to Stack Overflow.
-The issue tracker is an important place of record for design discussions and should be self-sufficient.
-
-Once you're ready, create an issue on https://github.com/spring-projects/spring-security/issues[GitHub].
-
-Many issues are caused by subtle behavior, typos, and unintended configuration.
-Creating a https://stackoverflow.com/help/minimal-reproducible-example[Minimal Reproducible Example] (starting with https://start.spring.io for example) of the problem helps the team quickly triage your issue and get to the core of the problem.
-
-We love contributors, and we may ask you to <<submit-a-pull-request,submit a PR with a fix>>.
-
-[[issue-lifecycle]]
-=== Issue Lifecycle
-
-When an issue is first created, it is flagged `waiting-for-triage` waiting for a team member to triage it.
-Once the issue has been reviewed, the team may ask for further information if needed, and based on the findings, the issue is either assigned a target branch (or no branch if a feature) or is closed with a specific status.
-The target branch is https://spring.io/projects/spring-security#support[the earliest supported branch] where <<choose-a-branch,the change will be applied>>.
-
-When a fix is ready, the issue is closed and may still be re-opened until the fix is released.
-After that the issue will typically no longer be reopened.
-In rare cases if the issue was not at all fixed, the issue may be re-opened.
-In most cases however any follow-up reports will need to be created as new issues with a fresh description.
-
-[[build-from-source]]
-=== Build from Source
-
-See https://github.com/spring-projects/spring-security/tree/main#building-from-source[Build from Source] for instructions on how to check out, build, and import the Spring Security source code into your IDE.
-
-[[code-style]]
-=== Source Code Style
-
-The wiki pages https://github.com/spring-projects/spring-framework/wiki/Code-Style[Code Style] and https://github.com/spring-projects/spring-framework/wiki/IntelliJ-IDEA-Editor-Settings[IntelliJ IDEA Editor Settings] define the source file coding standards we use along with some IDEA editor settings we customize.
-
-To format the code as well as check the style, run `./gradlew format && ./gradlew check`.
-
-[[submit-a-pull-request]]
-=== Submit a Pull Request
-
-We are excited for your pull request! :heart:
-
-Please do your best to follow these steps.
-Don't worry if you don't get them all correct the first time, we will help you.
-
-1. [[sign-cla]] All commits must include a __Signed-off-by__ trailer at the end of each commit message to indicate that the contributor agrees to the Developer Certificate of Origin.
-For additional details, please refer to the blog post https://spring.io/blog/2025/01/06/hello-dco-goodbye-cla-simplifying-contributions-to-spring[Hello DCO, Goodbye CLA: Simplifying Contributions to Spring].
-2. [[create-an-issue-list]] Must you https://github.com/spring-projects/spring-security/issues/new/choose[create an issue] first? No, but it is recommended for features and larger bug fixes. It's easier discuss with the team first to determine the right fix or enhancement.
-For typos and straightforward bug fixes, starting with a pull request is encouraged.
-Please include a description for context and motivation.
-Note that the team may close your pull request if it's not a fit for the project.
-3. [[choose-a-branch]] Always check out the branch indicated in the milestone and submit pull requests against it (for example, for milestone `5.8.3` use the `5.8.x` branch).
-If there is no milestone, choose `main`.
-Once merged, the fix will be forwarded-ported to applicable branches including `main`.
-4. [[create-a-local-branch]] Create a local branch
-If this is for an issue, consider a branch name with the issue number, like `gh-22276`.
-5. [[write-tests]] Add documentation and JUnit Tests for your changes.
-6. [[update-copyright]] In all files you edited, if the copyright header is of the form 2002-20xx, update the final copyright year to the current year.
-7. [[add-since]] If on `main`, add `@since` JavaDoc attributes to new public APIs that your PR adds
-8. [[change-rnc]] If you are updating the XSD, please instead update the RNC file and then run `./gradlew :spring-security-config:rncToXsd`.
-9. [[format-code]] For each commit, build the code using `./gradlew format && ./gradlew check`.
-This command ensures the code meets most of <<code-style,the style guide>>; a notable exception is import order.
-10. [[commit-atomically]] Choose the granularity of your commits consciously and squash commits that represent
-multiple edits or corrections of the same logical change.
-See https://git-scm.com/book/en/Git-Tools-Rewriting-History[Rewriting History section of Pro Git] for an overview of streamlining the commit history.
-11. [[format-commit-messages]] Format commit messages using 55 characters for the subject line, 72 characters per line
-for the description, followed by the issue fixed, for example, `Closes gh-22276`.
-See the https://git-scm.com/book/en/Distributed-Git-Contributing-to-a-Project#Commit-Guidelines[Commit Guidelines section of Pro Git] for best practices around commit messages, and use `git log` to see some examples.
-Favor imperative tense over present tense (use "Fix" instead of "Fixes"); avoid past tense (use "Fix" instead of "Fixed").
-+
-[indent=0]
----
-Address NullPointerException
-
-Closes gh-22276
----
-[[reference-issue]]
-1. If there is a prior issue, reference the GitHub issue number in the description of the pull request.

-
-If accepted, your contribution may be heavily modified as needed prior to merging.
-You will likely retain author attribution for your Git commits granted that the bulk of your changes remain intact.
-You may also be asked to rework the submission.
-
-If asked to make corrections, simply push the changes against the same branch, and your pull request will be updated.
-In other words, you do not need to create a new pull request when asked to make changes.
-When it is time to merge, you'll be asked to squash your commits.
-
-==== Participate in Reviews
-
-Helping to review pull requests is another great way to contribute.
-Your feedback can help to shape the implementation of new features.
-When reviewing pull requests, however, please refrain from approving or rejecting a PR unless you are a core committer for Spring Security.

-      by such Contributor that are necessarily infringed by their
-      Contribution(s) alone or by combination of their Contribution(s)
-      with the Work to which such Contribution(s) was submitted. If You

-      cross-claim or counterclaim in a lawsuit) alleging that the Work
-      or a Contribution incorporated within the Work constitutes direct
-      or contributory patent infringement, then any patent licenses
-      granted to You under this License for that Work shall terminate
-      as of the date such litigation is filed.
-
-   4. Redistribution. You may reproduce and distribute copies of the
-      Work or Derivative Works thereof in any medium, with or without
-      modifications, and in Source or Object form, provided that You
-      meet the following conditions:
-
-      (a) You must give any other recipients of the Work or
-          Derivative Works a copy of this License; and
-
-      (b) You must cause any modified files to carry prominent notices
-          stating that You changed the files; and
-
-      (c) You must retain, in the Source form of any Derivative Works
-          that You distribute, all copyright, patent, trademark, and
-          attribution notices from the Source form of the Work,
-          excluding those notices that do not pertain to any part of
-          the Derivative Works; and
-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          distribution, then any Derivative Works that You distribute must
-          include a readable copy of the attribution notices contained
-          within such NOTICE file, excluding those notices that do not
-          pertain to any part of the Derivative Works, in at least one
-          of the following places: within a NOTICE text file distributed
-          as part of the Derivative Works; within the Source form or
-          documentation, if provided along with the Derivative Works; or,
-          within a display generated by the Derivative Works, if and
-          wherever such third-party notices normally appear. The contents
-          of the NOTICE file are for informational purposes only and
-          do not modify the License. You may add Your own attribution
-          notices within Derivative Works that You distribute, alongside
-          or as an addendum to the NOTICE text from the Work, provided
-          that such additional attribution notices cannot be construed
-          as modifying the License.
-
-      You may add Your own copyright statement to Your modifications and
-      may provide additional or different license terms and conditions
-      for use, reproduction, or distribution of Your modifications, or
-      for any such Derivative Works as a whole, provided Your use,
-      reproduction, and distribution of the Work otherwise complies with
-      the conditions stated in this License.
-
-   5. Submission of Contributions. Unless You explicitly state otherwise,
-      any Contribution intentionally submitted for inclusion in the Work
-      by You to the Licensor shall be under the terms and conditions of
-      this License, without any additional terms or conditions.
-      Notwithstanding the above, nothing herein shall supersede or modify
-      the terms of any separate license agreement you may have executed
-      with Licensor regarding such Contributions.
-
-   6. Trademarks. This License does not grant permission to use the trade
-      names, trademarks, service marks, or product names of the Licensor,
-      except as required for reasonable and customary use in describing the
-      origin of the Work and reproducing the content of the NOTICE file.
-
-   7. Disclaimer of Warranty. Unless required by applicable law or
-      agreed to in writing, Licensor provides the Work (and each
-      Contributor provides its Contributions) on an "AS IS" BASIS,
-      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-      implied, including, without limitation, any warranties or conditions
-      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-      PARTICULAR PURPOSE. You are solely responsible for determining the
-      appropriateness of using or redistributing the Work and assume any
-      risks associated with Your exercise of permissions under this License.
-
-   8. Limitation of Liability. In no event and under no legal theory,
-      whether in tort (including negligence), contract, or otherwise,
-      unless required by applicable law (such as deliberate and grossly
-      negligent acts) or agreed to in writing, shall any Contributor be
-      liable to You for damages, including any direct, indirect, special,
-      incidental, or consequential damages of any character arising as a
-      result of this License or out of the use or inability to use the
-      Work (including but not limited to damages for loss of goodwill,
-      work stoppage, computer failure or malfunction, or any and all
-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
-      the Work or Derivative Works thereof, You may choose to offer,
-      and charge a fee for, acceptance of support, warranty, indemnity,
-      or other liability obligations and/or rights consistent with this
-      License. However, in accepting such obligations, You may act only
-      on Your own behalf and on Your sole responsibility, not on behalf
-      of any other Contributor, and only if You agree to indemnify,
-      defend, and hold each Contributor harmless for any liability
-      incurred by, or claims asserted against, such Contributor by reason
-      of your accepting any such warranty or additional liability.
-
-   END OF TERMS AND CONDITIONS
-
-   APPENDIX: How to apply the Apache License to your work.
-
-      To apply the Apache License to your work, attach the following
-      boilerplate notice, with the fields enclosed by brackets "{}"
-      replaced with your own identifying information. (Don't include
-      the brackets!)  The text should be enclosed in the appropriate
-      comment syntax for the file format. We also recommend that a
-      file or class name and description of purpose be included on the
-      same "printed page" as the copyright notice for easier
-      identification within third-party archives.

-
-[#update-dependencies]
-== Update dependencies
-
-Dependency versions are managed in the file xref:./gradle/libs.versions.toml[libs.versions.toml] and are automatically updated by xref:./.github/dependabot.yml[dependabot].
-
-[#check-all-issues-are-closed]
-== Check all issues are closed
-
-The first step of a release is to check if there are any open issues remaining in a milestone.
-
-NOTE: A scheduled release will not proceed if there are any open issues.
-
-TIP: If you need to prevent a release from occurring automatically, the easiest way to block a release is to add an unresolved issue to the milestone.
-
-The https://github.com/spring-io/spring-security-release-tools/blob/main/release-plugin/README.adoc#checkMilestoneHasNoOpenIssues[`checkMilestoneHasOpenIssues`] command will check if there are any open issues for the release.
-Before running the command manually, replace the following values:
-
-* `<next-version>` - Replace with the title of the milestone you are releasing now (i.e. 5.5.0-RC1)
-* `<github-personal-access-token>` - Replace with a https://github.com/settings/tokens[GitHub personal access token] that has a scope of `public_repo`. This is optional since you are unlikely to reach the rate limit for such a simple check.
-
-[source,bash]
----
-./gradlew checkMilestoneHasOpenIssues -PnextVersion=<next-version> -PgitHubAccessToken=<github-personal-access-token>
----
-
-Alternatively, you can manually check using the https://github.com/spring-projects/spring-security/milestones[milestones] page.
-
-[#update-release-version]
-== Update release version
-
-If all issues for the release are <<check-all-issues-are-closed,closed>>, the version number is automatically updated using the milestone title.
-When performing this step manually, update the version number in `gradle.properties` for the release (for example `5.5.0`) and commit the change using the message "Release x.y.z".
-
-[#tag-release]
-== Tag release
-
-The release will automatically be tagged using the milestone title.
-It is not required to tag manually.
-However, you can perform this step manually by running the following command:
-
-[source,bash]
----
-git tag 5.5.0
----
-
-[#push-release-commit]
-== Push release commit
-
-During a scheduled release, the release commit will automatically be pushed to trigger a build.
-If performing this step manually, you can push the commit and tag and GitHub actions will build and deploy the artifacts with the following command:
-
-[source,bash]
----
-git push --atomic origin main 5.5.0
----
-
-The build will automatically wait for artifacts to be released to Maven Central.
-You can get notified manually when uploading is complete by running the following:
-
-[source,bash]
----
-./scripts/release/wait-for-done.sh 5.5.0
----
-
-[#build-locally]
-== Build
-
-All checks will automatically be performed by the build prior to uploading the artifacts to Maven Central.
-If something goes wrong, you can run the build locally using:
-
-[source,bash]
----
-./gradlew check
----
-
-[#update-release-notes-on-github]
-== Update release notes on GitHub
-
-Once the release has been uploaded to Maven Central, release notes will automatically be generated and a GitHub release will be created.
-To do this manually, you can use the https://github.com/spring-io/spring-security-release-tools/blob/main/release-plugin/README.adoc#generateChangelog[`generateChangelog`] command to generate the release notes by replacing:
-
-* `<next-version>` - Replace with the milestone you are releasing now (i.e. 5.5.0)
-
-[source,bash]
----
-./gradlew generateChangelog -PnextVersion=<next-version>
----
-
-Then copy the release notes to your clipboard (your mileage may vary with the following command):
-
-[source,bash]
----
-cat build/changelog/release-notes.md | xclip -selection clipboard
----
-
-Finally, create the
-https://github.com/spring-projects/spring-security/releases[release on
-GitHub], associate it with the tag, and paste the generated notes.
-
-Alternatively, you can run the https://github.com/spring-io/spring-security-release-tools/blob/main/release-plugin/README.adoc#createGitHubRelease[`createGitHubRelease`] command to perform these steps automatically, replacing:
-
-* `<next-version>` - Replace with the milestone you are releasing now (i.e. 5.5.0)
-* `<branch>` - The name of the branch to be tagged (if the release commit has not already been tagged)
-* `<github-personal-access-token>` - Replace with a https://github.com/settings/tokens[GitHub personal access token] that has a scope of `write:org`
-
-[source,bash]
----
-./gradlew createGitHubRelease -PnextVersion=<next-version> -Pbranch=<branch> -PcreateRelease=true -PgitHubAccessToken=<github-personal-access-token>
----
-
-[#update-version-on-project-page]
-== Update version on project page
-
-The build will automatically update the project versions on https://spring.io/projects/spring-security#learn.
-To do this manually, you can use the https://github.com/spring-io/spring-security-release-tools/blob/main/release-plugin/README.adoc#createSaganRelease[`createSaganRelease`] and https://github.com/spring-io/spring-security-release-tools/blob/main/release-plugin/README.adoc#deleteSaganRelease[`deleteSaganRelease`] commands using the following parameters:
-
-* `<next-version>` - Replace with the milestone you are releasing now (i.e. 5.5.0)
-* `<previous-version>` - Replace with the previous release which will be removed from the listed versions (i.e. 5.5.0-RC1)
-* `<github-personal-access-token>` - Replace with a https://github.com/settings/tokens[GitHub personal access token] that has a scope of `read:org` as https://spring.io/restdocs/index.html#authentication[documented for spring.io api]
-
-[source,bash]
----
-./gradlew createSaganRelease deleteSaganRelease -PnextVersion=<next-version> -PpreviousVersion=<previous-version> -PgitHubAccessToken=<github-personal-access-token>
----
-
-Alternatively, you can log into Contentful and update the versions manually on the Spring Security project page.
-
-[#close-create-milestone]
-== Close / Create milestone
-
-The release milestone will be automatically closed once the release is complete.
-To proceed manually, perform the following steps:
-
-1. Visit https://github.com/spring-projects/spring-security/milestones[GitHub
-Milestones] and create a new milestone for the next release version
-2. Move any open issues from the existing milestone you just released to the new milestone
-3. Close the milestone for the release
-
-NOTE: Remember that scheduled releases <<check-all-issues-are-closed,will not proceed>> if there are still open issues in the milestone.
-
-[#announce-release-on-slack]
-== Announce release on Slack
-
-The release will automatically be announced on Slack.
-If proceeding manually, announce the release on Slack in the channel https://pivotal.slack.com/messages/spring-release[#spring-release], including the keyword `+spring-security-announcing+` in the message.
-Something like:
-
-....
-spring-security-announcing `5.5.0` is available now
-....
-
-[#update-to-next-development-version]
-== Update to next development version
-
-After the release is complete and artifacts have been uploaded to Maven Central, the build will automatically update to the next development version, commit and push.
-If proceeding manually, update the version in `gradle.properties` to the next `+SNAPSHOT+` version with the commit message "Next development version" and then push.
-
-[#announce-release-on-other-channels]
-== Announce release on other channels
-
-* Create a blog post on Contentful
-* Tweet from https://twitter.com/springsecurity[@SpringSecurity]
-
-[[frequently-asked-questions]]
-== Frequently Asked Questions
-
-*When should I update dependencies manually?* Dependencies should be updated at the latest the end of the week prior to the release. This is usually the Friday following the 2nd Monday of the month (counting from the first week with a Monday). When in doubt, check the https://github.com/spring-projects/spring-security/milestones[milestones] page for release due dates.
-
-*When do scheduled releases occur?* Automated releases are scheduled to occur at *3:15 PM UTC* on the *3rd Monday of the month* (counting from the first week with a Monday).
-
-[NOTE]
-The scheduled release process currently runs every Monday but only releases when a release is due. See the performed checks below for more information.
-
-The automated release process occurs on the following branches:
-
-* `main`
-* `6.2.x`
-* `6.1.x`
-* `6.0.x` (commercial only)
-* `5.8.x`
-
-For each of the above branches, the automated process performs the following checks before proceeding with the release:
-
-1. _Check if the milestone is due today._ This check compares the current (SNAPSHOT) version of the branch with available milestones and chooses the first match (sorted alphabetically). If the due date on the matched milestone is *not* today, the process stops.
-2. _Check if all issues are closed._ This check uses the milestone from the previous step and looks for open issues. If any open issues are found, the process stops.
-
-[IMPORTANT]
-You should ensure all issues are closed or moved to another milestone prior to a scheduled release.
-
-If the above checks pass, the version number is updated (in `gradle.properties`) and a commit is pushed to trigger the CI process.
-
-*How do I trigger a release manually?* You can trigger a release manually in two ways:
-
-1. Trigger a release for a particular branch via https://github.com/spring-projects/spring-security/actions/workflows/update-scheduled-release-version.yml[`update-scheduled-release-version.yml`] on the desired branch. The above checks are performed for that branch, and the release will proceed if all checks pass. _This is the recommended way to trigger a release that did not pass the above checks during a regularly scheduled release._
-2. Trigger releases for all branches via https://github.com/spring-projects/spring-security/actions/workflows/release-scheduler.yml[`release-scheduler.yml`] on the `main` branch. The above checks are performed for each branch, and only releases that pass all checks will proceed.
-
-*When should additional manual steps be performed?* All other automated steps listed above occur during the normal CI process. Additional manual steps can be performed at any time once the builds pass and releases are finished.
-
-*What if something goes wrong?* If the normal CI process fails, you can retry by re-running the failed jobs with the "Re-run failed jobs" option in GitHub Actions. If changes are required, you should revert the "Release x.y.z" commit, delete the tag, and proceed manually.

- * The <tt>AclService</tt> is used to retrieve the access control list (ACL) permissions
- * associated with a domain object instance for the current <tt>Authentication</tt>
- * object.
- * <p>
- * The voter will vote if any {@link ConfigAttribute#getAttribute()} matches the
- * {@link #processConfigAttribute}. The provider will then locate the first method
- * argument of type {@link #processDomainObjectClass}. Assuming that method argument is
- * non-null, the provider will then lookup the ACLs from the <code>AclManager</code> and
- * ensure the principal is {@link Acl#isGranted(List, List, boolean)} when presenting the
- * {@link #requirePermission} array to that method.
- * <p>
- * If the method argument is <tt>null</tt>, the voter will abstain from voting. If the
- * method argument could not be found, an {@link AuthorizationServiceException} will be
- * thrown.
- * <p>
- * In practical terms users will typically setup a number of <tt>AclEntryVoter</tt>s. Each
- * will have a different {@link #setProcessDomainObjectClass processDomainObjectClass},
- * {@link #processConfigAttribute} and {@link #requirePermission} combination. For
- * example, a small application might employ the following instances of

- * <ul>
- * <li>Process domain object class <code>BankAccount</code>, configuration attribute
- * <code>VOTE_ACL_BANK_ACCONT_READ</code>, require permission
- * <code>BasePermission.READ</code></li>
- * <li>Process domain object class <code>BankAccount</code>, configuration attribute
- * <code>VOTE_ACL_BANK_ACCOUNT_WRITE</code>, require permission list
- * <code>BasePermission.WRITE</code> and <code>BasePermission.CREATE</code> (allowing the
- * principal to have <b>either</b> of these two permissions)</li>
- * <li>Process domain object class <code>Customer</code>, configuration attribute
- * <code>VOTE_ACL_CUSTOMER_READ</code>, require permission
- * <code>BasePermission.READ</code></li>
- * <li>Process domain object class <code>Customer</code>, configuration attribute
- * <code>VOTE_ACL_CUSTOMER_WRITE</code>, require permission list
- * <code>BasePermission.WRITE</code> and <code>BasePermission.CREATE</code></li>
- * </ul>
- * Alternatively, you could have used a common superclass or interface for the
- * {@link #processDomainObjectClass} if both <code>BankAccount</code> and
- * <code>Customer</code> had common parents.
- *
- * <p>
- * If the principal does not have sufficient permissions, the voter will vote to deny
- * access.
- *
- * <p>
- * All comparisons and prefixes are case sensitive.

-/**
- * Given a domain object instance returned from a secure object invocation, ensures the

- * The <code>AclService</code> is used to retrieve the access control list (ACL)
- * permissions associated with a domain object instance for the current
- * <code>Authentication</code> object.
- * <p>
- * This after invocation provider will fire if any {@link ConfigAttribute#getAttribute()}
- * matches the {@link #processConfigAttribute}. The provider will then lookup the ACLs
- * from the <tt>AclService</tt> and ensure the principal is
- * {@link org.springframework.security.acls.model.Acl#isGranted(List, List, boolean)
- * Acl.isGranted(List, List, boolean)} when presenting the {@link #requirePermission}
- * array to that method.
- * <p>
- * Often users will set up an <code>AclEntryAfterInvocationProvider</code> with a
- * {@link #processConfigAttribute} of <code>AFTER_ACL_READ</code> and a
- * {@link #requirePermission} of <code>BasePermission.READ</code>. These are also the
- * defaults.
- * <p>
- * If the principal does not have sufficient permissions, an
- * <code>AccessDeniedException</code> will be thrown.
- * <p>
- * If the provided <tt>returnedObject</tt> is <code>null</code>, permission will always be
- * granted and <code>null</code> will be returned.
- * <p>
- * All comparisons and prefixes are case sensitive.
- *
- * @deprecated please use {@link AclPermissionEvaluator} instead. Spring Method Security
- * annotations may also prove useful, for example
- * {@code @PostAuthorize("hasPermission(filterObject, read)")}
