## Issues Found and Fixed

### Issue 1: SecurityMemberAccessProxyTest (Spring Plugin)

**Location**: `plugins/spring/src/test/java/org/apache/struts2/ognl/SecurityMemberAccessProxyTest.java`

**Problem**: The test created `SecurityMemberAccess` as a field with `new SecurityMemberAccess(null, null)` without
injecting `ProxyService`, causing NullPointerException.

**Fix Applied**:

```java
// Added imports
import org.apache.struts2.util.StrutsProxyService;
import org.apache.struts2.util.ProxyService;

// Changed field declaration
private SecurityMemberAccess sma;
private ProxyService proxyService;

// Added to setUp()
proxyService = new StrutsProxyService(new StrutsProxyCacheFactory<>("1000", "basic"));
sma = new SecurityMemberAccess(null, null);
sma.setProxyService(proxyService);
```

### Issue 2: JSONResultTest (JSON Plugin)

**Location**: `plugins/json/src/test/java/org/apache/struts2/json/JSONResultTest.java`

**Problem**: The test `testNotTraverseOrIncludeProxyInfo` created `DefaultJSONWriter` directly without injecting
`ProxyService`, causing NullPointerException when processing Spring proxies.

**Fix Applied**:

```java
// Added imports
import org.apache.struts2.ognl.StrutsProxyCacheFactory;
import org.apache.struts2.util.StrutsProxyService;
import org.apache.struts2.util.ProxyService;

// Added field
ProxyService proxyService;

// Added to setUp()
this.proxyService = new StrutsProxyService(new StrutsProxyCacheFactory<>("1000", "basic"));

// Updated testNotTraverseOrIncludeProxyInfo()
DefaultJSONWriter writer = new DefaultJSONWriter();
writer.setProxyService(proxyService);
```

## Configuration Properties Verified

| Property                    | Default Value | Purpose                               |
|-----------------------------|---------------|---------------------------------------|
| `struts.proxy.cacheType`    | `basic`       | Cache implementation (basic/caffeine) |
| `struts.proxy.cacheMaxSize` | `10000`       | Maximum cache entries                 |
| `struts.proxy.cacheFactory` | `struts`      | Factory implementation name           |
| `struts.proxyService`       | `struts`      | Service implementation name           |

## Success Criteria Status

| Criterion                                                | Status            |
|----------------------------------------------------------|-------------------|
| Build passes: `mvn clean install -DskipTests`            | ✅ PASS            |
| Unit tests pass: New tests                               | ✅ PASS (17 tests) |
| Updated tests pass: Core tests                           | ✅ PASS (81 tests) |
| Full test suite: `mvn test -DskipAssembly`               | ✅ PASS            |
| No Caffeine required with `struts.proxy.cacheType=basic` | ✅ VERIFIED        |

## Minor Gap Identified

**SpringProxyUtilTest.java** - Not updated to test `ProxyService` alongside deprecated `ProxyUtil`

- **Impact**: Low - tests deprecated API which still works
- **Recommendation**: Can be addressed in follow-up if needed

## Conclusion

The WW-5514 implementation is **complete and validated**. Two test files in plugin modules required additional fixes for
`ProxyService` injection that were not identified in the original research document. All tests now pass successfully.
