Comment 2 Tomas Danek 2012-02-22 13:49:52 UTC 
one more (maybe) useful info: debugger appeared to hit breakpoint (got notification in debugger window), but line with BP did not turn green.
Comment 3 Marian Mirilovic 2012-02-24 14:52:28 UTC 
Might be JDK7u4 related .... is anybody able to reproduce it on another JDK and what about OS ?
Comment 4 Martin Entlicher 2012-02-24 15:44:58 UTC 
IMHO it's Mac-specific. I didn't see it on a different platform.
Comment 5 Martin Entlicher 2012-02-27 14:56:44 UTC 
The exception is fixed by changeset:   213798:48cb21c44a79

I've submitted issue #208904 to check the mouse grab problem on Mac OS X.

Tomasi, can you please verify this issue? I only have Snow Leopard. :( Thanks!
Comment 8 Martin Entlicher 2012-03-22 10:38:21 UTC 
I do not think the assignment should be changed when asking for verification...
Comment 9 Tomas Danek 2012-03-22 11:28:01 UTC

Not really fixed - see issue #209926.

Comment 12 Martin Entlicher 2012-03-22 11:54:33 UTC 
The problem is, that we're catching an exception, but an Error is thrown.
Comment 13 Martin Entlicher 2012-03-22 12:21:32 UTC 
Hopefully, you'll not get the exception any more...
