Gregory Shimansky commented on HARMONY-1650:
--------------------------------------------
I tried this test on gentoo linux and it doesn't fail for me as well. Maybe it requires more than 1 CPU?

> Memory allocation within VM causes irregularly enqueuing references, doing finalization, running
> finalizers. These processes lead to losing an exception risen within a java programm executed by VM.

> So, this intricated enough bug leads to instability of VM's behaviour.
> I'm going to attach the fix of the issue.
> The detecting test will be attached as well.
