Hi Jai, I don't think the memory size comes into play, the GC is invoked directly and WeakReferences should be cleared independently from memory pressure.  Adding a memory max might be harmless, but it would not be clear whether it was really a factor.

As for the -Xcheck:jni, it's a left over from when the test was constructed and run as a single main.
There is no explicit JNI usage in the test and the test logic does not depend on that setting.
It should be removed to avoid future confusion.  Thanks for the observations.
