* WW-5537 Add Container.destroy() to clear internal caches on undeploy
Container now exposes a destroy() method that clears factories, injectors,
constructors, and ThreadLocals. This releases Class<?> keys and JDK
DelegatingClassLoader instances that pin the webapp classloader.
DefaultConfiguration.destroy() calls container.destroy() and
reloadContainer() delegates to destroy() to avoid duplication.
Also fixes JSONCacheDestroyable referencing non-existent DefaultJSONWriter
(renamed to StrutsJSONWriter).

* WW-5537 Fix Container.destroy(): don't clear factories, don't call from reloadContainer
factories must remain intact because existing code holds direct
references to the Container after destroyConfiguration() and expects
it to still resolve dependencies (e.g. during configuration reload).
reloadContainer() reverted to clearing packageContexts/loadedFileNames
directly — calling destroy() there nulled the container reference and
cleared state needed during the bootstrap transition.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* WW-5537 Restore destroy() call in reloadContainer()
The test failures were caused by factories.clear() in
Container.destroy(), not by calling destroy() from reloadContainer().
Now that factories.clear() is removed, destroy() is safe to call
here — it clears packageContexts, loadedFileNames, and the container's
reflection caches in one place.

Add configurable limits to the JSON plugin to prevent denial-of-service
attacks via malicious payloads (deeply nested objects, huge arrays, long
strings).
Changes:
- Extract JSONReader interface from class, create StrutsJSONReader impl
with maxElements, maxDepth, maxStringLength, maxKeyLength enforcement
- Rename DefaultJSONWriter to StrutsJSONWriter (Struts* naming convention)
- Add JSONBeanSelectionProvider for bean aliasing via constants
- Update JSONUtil with @Inject for reader/writer, add instance
deserializeInput() with maxLength check, deprecate static deserialize()
- Wire limits into JSONInterceptor with @Inject from constants
- Register beans and defaults in struts-plugin.xml
Default limits: 10K elements, 64 depth, 2MB length, 256KB strings, 512 keys.
All configurable via struts.xml constants or per-action interceptor params.

* feat(proxy): WW-5514 add StrutsProxyService for proxy detection and resolution
Introduces a configurable ProxyService interface and StrutsProxyService
implementation for detecting and resolving Spring AOP/Hibernate proxies.
Key changes:
- Add ProxyService interface with isProxy, ultimateTargetClass, and
resolveTargetMember methods
- Add StrutsProxyService implementation using configurable caches
- Add ProxyCacheFactory and StrutsProxyCacheFactory for cache management
- Integrate ProxyService into ChainingInterceptor, ParametersInterceptor,
and SecurityMemberAccess
- Add integration test with Spring AOP proxied action chaining
- Add configuration constants for proxy cache type and size
The StrutsProxyService correctly handles:
- Spring CGLIB proxies (class-based)
- Spring JDK dynamic proxies (interface-based)
- Hibernate entity proxies
- Member resolution for allowlist checking

The duplicate @Action name detection in PackageBasedActionConfigBuilder
was embedded inside a conditional block that only ran when execute() was
NOT annotated with @Action. This meant two methods could map to the same
action name silently when execute() had an @Action annotation, with one
overwriting the other non-deterministically.
Extract the duplicate check to run unconditionally before the conditional
block, so it applies to all annotated methods regardless of whether
execute() is annotated.

Change the default value of struts.objectFactory.spring.autoWire.alwaysRespect
from false to true to fix the Spring constructor autowiring issue.
When a Spring String bean exists (e.g., JNDI lookup with default-value),
Spring's AUTOWIRE_CONSTRUCTOR strategy incorrectly injects that value into
ALL String parameters of ServletActionRedirectResult constructors, causing
malformed redirect URLs.
Setting alwaysRespect to true by default ensures the configured autowire
strategy (AUTOWIRE_BY_NAME) is consistently used, preventing unintended
bean injection.
Users who rely on the legacy constructor autowiring behavior can restore
it by setting:
<constant name="struts.objectFactory.spring.autoWire.alwaysRespect" value="false" />

Implement two-phase processing for conversion properties to enable
Spring bean name resolution in struts-conversion.properties files.
The issue was a timing problem: type converters were processed during
bootstrap phase before SpringObjectFactory was available. Now:
- Early phase: process struts-default-conversion.properties (class names)
- Late phase: process user properties when SpringObjectFactory is ready
Changes:
- Add UserConversionPropertiesProvider interface for late initialization
- Add UserConversionPropertiesProcessor to trigger late phase processing
- Split StrutsConversionPropertiesProcessor.init() into early/late phases
- Register new beans in DefaultConfiguration and struts-beans.xml
- Add alias in StrutsBeanSelectionProvider for dependency injection
- Improve JavaDocs for BeanSelectionProvider classes

* feat(ognl): implement OGNL 3.4.8 compatibility changes
Implement comprehensive code changes to support OGNL 3.4.8 upgrade:
- Create StrutsContext wrapper extending OgnlContext for type-safe context operations
- Update 13 PropertyAccessor implementations: change Map context to OgnlContext
(XWorkObjectPropertyAccessor, XWorkCollectionPropertyAccessor, XWorkMapPropertyAccessor,
XWorkListPropertyAccessor, XWorkIteratorPropertyAccessor, XWorkEnumerationAccessor,
ParameterPropertyAccessor, ObjectProxyPropertyAccessor, ObjectAccessor,
HttpParametersPropertyAccessor, CompoundRootAccessor, XWorkMethodAccessor)
- Update TypeConverter implementations: OgnlTypeConverterWrapper, XWorkTypeConverterWrapper
- Update NullHandler implementation: OgnlNullHandlerWrapper
- Update SecurityMemberAccess interface methods to use OgnlContext
- Update createDefaultContext return type from Map to OgnlContext in OgnlUtil and OgnlReflectionContextFactory
- Fix OgnlUtil method calls with proper OgnlContext casting
- Fix OgnlReflectionProvider: remove obsolete exception handling
- Update CompoundRootAccessor: remove unnecessary exception handling
Breaking API changes in OGNL 3.4.8:
- PropertyAccessor: getProperty/setProperty methods now require OgnlContext instead of Map
- TypeConverter: convertValue method now requires OgnlContext and uses Class<?> generic
- NullHandler: nullMethodResult/nullPropertyValue methods now require OgnlContext
- Ognl.createDefaultContext: returns OgnlContext instead of Map
- OgnlRuntime methods: simplified signatures without OgnlContext where not needed
This commit addresses the binary-incompatible API changes introduced in OGNL 3.4.8
as detailed in the research document.

* feat(ognl): add ensureOgnlContext for backward compatibility
Add ensureOgnlContext() helper method to handle cases where HashMap
is passed instead of OgnlContext. This provides backward compatibility
for code that still passes plain Map objects to setProperties() and
setProperty() methods.
The method checks if the context is already an OgnlContext and returns
it as-is, otherwise creates a new OgnlContext and copies the Map contents.
This fixes ClassCastException errors in validation interceptor tests where
legacy code passes HashMap contexts during validator initialization.
Fixes:
- DefaultWorkflowInterceptorTest (12 tests)
- ValidationInterceptorPrefixMethodInvocationTest (2 tests)
- ValidationErrorAwareTest (2 tests)

- Explicitly configure security flags (test container doesn't load

The Struts IDEA plugin incorrectly displayed xwork-default.xml as a

- Copy struts-tests-default.xml to plugins/spring/src/test/resources

The exclusion pattern "org.apache.struts2.*" was not properly excluding
classes directly in the root package (like XWorkTestCase) because:
1. PackageBasedActionConfigBuilder extracts package names using
substringBeforeLast(className, ".") which produces "org.apache.struts2"
(no trailing dot)
2. The wildcard pattern requires a literal "." before "*"
3. Result: Pattern doesn't match root package classes
Fix: Enhanced checkExcludePackages() to automatically handle patterns
ending with ".*" by also checking if the package name equals the base
pattern (without ".*").
Now "org.apache.struts2.*" properly excludes both:
- Classes in root package: org.apache.struts2.XWorkTestCase
- Classes in subpackages: org.apache.struts2.dispatcher.SomeClass
