Could you add some more work for GC here: add and free objects, arrays, strings and free them. Then call WB.GC to ensure that GC is triggered.
You could add the corresponding method in GarbageUtils and always use it instead eatMemory.

Might be call WB.YoungGC while generating garbage to put something into old gen as well as in young gen
