nice catch, I guess I assumed that the test makes sure its child JVMs are run in the correct setting (as `CompressedOopsTest.java` does). I'll update the test to pass `-XX:+ClassUnloading` in `ClassLoadUnloadTest::exec`.

this test explicitly passes `-XX:+UseCompressedOops` to a child JVM, so the condition hasn't been weakened, if anything this change increases the coverage for JVMs where `UseCompressedOops` isn't true by default as now the test will be included in out-of-box runs.
