I'm seeing this issue regularly. I can provide additional thread dumps if necessary.

Comment 6 rptmaestro 2015-03-07 07:35:36 UTC

Also, I've used this same version of the IDE on Windows, Linux, and Mac OS X. I only ever see this issue on the Mac OS X.

Actually what's more interesting than a thread dump is a heap dump. So when this happens can you make a heap dump using VisualVM?
