Thanks for checking! It looks like `testThreadGroupName` timed out. Not related our changes to `testClassName`. 

The problem is that all the tests in this class, `TestObjectDescription`, rely on probabilistic sampling. So they are flakey. There's a chance that the desired objects never gets sampled. 

I've pushed another commit disabling TLABs `-XX:-UseTLAB`. This should force each allocation to get sampled. I also reduced the number of allocations per iteration (since sampling is now guaranteed). The only way we can time-out now is if undesired allocations push all the desired allocations out of the leak profiler queue.
