parallel garbage collector?

I haven't tried parallel GC, however FileWatcher2K.dll is part of IntelliJ,
used to look for files changing in the underlying (Win32) filesystem and
allowing IDEA to automatically resync them. I guess this means there's a
bug in their DLL that's only triggered by the parallel GC, however if you
can live without that syncing functionality then it should be OK to just
delete/rename the DLL and run IDEA without it.

Was anyone successful in running idea with parallel GC? For me, it
crashes periodically, always in the same native code...

1. Java VM: Java HotSpot(TM) Client VM (1.5.0_06-b05 mixed mode)

2. Problematic frame:

3. C

Upgrading to 5.1.2 should fix the problem with file watcher.
