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...

Upgrading to 5.1.2 should fix the problem with file watcher.
