I have been unable to reproduce the timout error in `LogGeneratedClassesTest` locally on a `x86_64 Linux` machine with jdk11, jdk17 and jdk21. I was able to reproduce the intermittent assert...

@tajila given the intermittent assert error in `LogGeneratedClassesTest.testDumpDirIsFile`, where the error message appears twice in two separate threads (`main thread` and `Attach API initializer`), and considering that the test does...

> Do you know what causes the init failure exactly? is it a missing class The init failure is caused by the absence of [`ClassFileDumper`](https://github.com/ibmruntimes/openj9-openjdk-jdk21/blob/04179e57eb81a73b69928a58c9c299edc792278d/src/java.base/share/classes/jdk/internal/util/ClassFileDumper.java#L169) which is requested during the...

I am unable to reproduce the issue locally on a `ppc64le linux` machine `cent8le-rtp-rt6-1`, which is where the issue occurred in the past, after running the test [CpMpJlinkTest](https://github.com/adoptium/aqa-systemtest/blob/00de74587e5ac2849df0409a00699f21e39c824d/openjdk.test.modularity/src/com.stf/net/adoptopenjdk/test/modularity/CpMpJlinkTest.java) with [aqa-systemtest](https://github.com/adoptium/aqa-systemtest/blob/00de74587e5ac2849df0409a00699f21e39c824d/openjdk.build/docs/build.md)...

The intermittent [CpMpJlinkTest](https://github.com/adoptium/aqa-systemtest/blob/00de74587e5ac2849df0409a00699f21e39c824d/openjdk.test.modularity/src/com.stf/net/adoptopenjdk/test/modularity/CpMpJlinkTest.java) failure is reproducible in a [grinder](https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/38846/) that runs the test for 1000 iterations on a `ppc64le linux` machine. The issue also occurs in a [grinder](https://hyc-runtimes-jenkins.swg-devops.com/job/Grinder/38880/) with `-Xint`.

It seems like `-Xint` is not getting to the jvm that is run by the [jlink command](https://github.com/adoptium/aqa-systemtest/blob/00de74587e5ac2849df0409a00699f21e39c824d/openjdk.test.modularity/src/com.stf/net/adoptopenjdk/test/modularity/CpMpJlinkTest.java#L82-L101) in `CpMpJlinkTest`, which is where the `ClassCastException` occurs, when creating an image. `jlink`...

The [OPENJ9_JAVA_OPTIONS](https://eclipse.dev/openj9/docs/cmdline_specifying/) environment variable was set to `-Xint` in a modified [CpMpJlinkTest](https://github.com/singh264/aqa-systemtest/commit/4212e8e3f45192a3df9a5c40ec342cbb6e434fd4) to ensure `-Xint` gets to the jvm that is run by the [jlink command](https://github.com/singh264/aqa-systemtest/commit/4212e8e3f45192a3df9a5c40ec342cbb6e434fd4#diff-9c59b782d243f773d92f82503528c91c6106b86c4ac8609061ce803c1c90bd83R83-R102) in the test.

However, the `jlink` command in the test does...
