JDK8 Test failures on test-docker-alpine320-x64-2 and -3 but not -4

In the october release we saw test failures appear on test-docker-alpine320-x64-2 and -3 but not -4.

JDK8 triage https://github.com/adoptium/aqa-tests/issues/6689#issuecomment-3442690729

The mauve system failures were [solved](https://github.com/adoptium/infrastructure/issues/4123) by clearing the `externalDependency` cache directory. However the following failures persist:

**Sanity openjdk**

```
java/util/ResourceBundle/Control/StressTest.java
java/util/concurrent/forkjoin/Integrate.java
java/util/concurrent/forkjoin/NQueensCS.java
```

**sanity system**

```
ParallelStreamsLoadTest_HS_0
ParallelStreamsLoadTest_HS_1
```

There were various failures from **extended openjdk**. I'm rerunning them on [-2](https://ci.adoptium.net/job/Grinder/15406/console) and [-3](https://ci.adoptium.net/job/Grinder/15407/console)

Start with the linked JDK8 triage comment and compare the Grinder runs 15406 and 15407 for test-docker-alpine320-x64-2 and -3 against -4. Review the listed sanity and extended OpenJDK failures, including the ParallelStreamsLoadTest failures. Done means identifying why the failures persist and documenting or applying the appropriate infrastructure resolution.
