Profiler snapshot after this happens

I think this may be more serious than P2. After it happened, the IDE started to take 100% of processor, and the Mac dock stopped working - I needed to shut down the IDE. I am attaching a profiler snapshot after this happened: Thread-65 looks suspicious.

I will also comment in the JavaFX bug (RT-24337).
Comment 5 Petr Jiricka 2012-10-19 09:56:34 UTC 
I meant "more serious than P3".
Comment 6 Marian Mirilovic 2012-10-19 10:08:36 UTC 
Petr, thanks for comments (also for comments in JavaFX bug), we might think of increasing the priority of their bug, Tondo ?
Comment 7 Antonin Nebuzelsky 2012-10-19 10:18:35 UTC 
(In reply to comment #6)
> Tondo ?

I agree, let's increase the priority in javafx-jira.

Petr, can you do it based on your comment that you entered there? Thanks.
Comment 8 Petr Jiricka 2012-10-19 10:34:31 UTC 
Ok, increased to Major.
