Description tkhh 2010-08-12 18:27:43 UTC 
I'm trying to create a new form and Netbeans 6.9.1 runs into a deadlock.
When running from a completely unmodified install with plain default config, it works.

Looking at the Netbeans process with JConsole tells me that there is a Thread deadlock between AWT-EventQueue-1 and GUI Builder. Please see stack traces below (copied from Deadlock tab in JConsole):

Comment 1 tkhh 2010-08-12 19:51:25 UTC 
I can add, that the problem went away after removing the config settings under
<userdir>/config/FormDesignerPalette.

I had an additional palette defined (which is still valid), but the config entries for that don't seem to work anymore.
Comment 2 Tomas Pavek 2010-08-16 17:09:07 UTC 
What is your JDK version? You might have run into bug 187697.
Comment 3 tkhh 2010-08-16 17:20:52 UTC 
Thanks for pointing me to that bug.

Yes it is jdk6u21, and probably the palette contained a SwingX component.
The workaround (remove/rebuild the additional palette) is OK for us right now.
But a fix in the JDK would of course eventually help. 

It sounds like jdk6u20 would still work? This could help to survive if we need SwingX.
Comment 4 Tomas Pavek 2010-08-17 08:28:20 UTC 
Yes, jdk6u20 should work. Let us know if it does not in your case.
