3 thread dumps taken after each other

It happened to me twice today while I was working with HTML editor, the last time it was:
 - some HTML page from project A was running in Chrome with NB integration
 - I opened HTML page from project B and start editing
 - after (in this case) inserting table using Palette, cursor changed to busy state ("circle with rainbow color") and UI became irresponsive but I can see the memory bar in toolbar is still being updated, but I cannot interact with IDE in any way.

I'm attaching 3 thread dumps taken several seconds apart each other.

Comment 3 Vladimir Riha 2013-08-13 10:35:29 UTC 
I've just seen it with XHTML but all my attempts to take thread dump were unsuccessful (I tried jvisualvm, jstack and plain old kill -QUIT). Please evaluate.  

Same OS, JDK and build as in description
Comment 4 Marek Fukala 2013-08-13 13:13:44 UTC 
Very similar to issue 218897 - deadlock between EDT and AppKit thread - a JDK bug however supposedly fixed in 7u10 b12.
Comment 5 Marek Fukala 2013-08-13 13:25:21 UTC 
Passing to platform upon agreement with Standa. 

Just from the glimpse to the original JDK bug [1] the evaluation and fix seems strange to me.

Comment 6 Vladimir Riha 2013-08-13 13:29:04 UTC 
Thank you Marku, I'm trying to reproduce but without luck
Comment 7 Stanislav Aubrecht 2013-08-28 14:01:11 UTC 
I noticed there is a NPE from our dnd support in the log. That NPE may put the AppKit thread into undefined state (it seems to be stuck in sun.awt.dnd.SunDropTargetContextPeer.handleDropMessage).

I fixed that NPE in core-main 8beba30b693c, please reopen if still reproducible, thanks.
Comment 8 Vladimir Riha 2013-08-28 14:04:20 UTC 
Of course, will do. Thank you.

Integrated into 'main-silver', will be available in build *201309010001* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
