Description Petr Dvorak 2009-12-18 04:54:38 UTC 
Product Version: NetBeans IDE 6.8 (Build 200912041610)
Java: 1.6.0_17; Java HotSpot(TM) 64-Bit Server VM 14.3-b01-101
System: Mac OS X version 10.5.8 running on x86_64; MacRoman; en_US (nb)

I created a new JPanel in existing JavaApplication - then NB IDE froze. No scanning or any other activity was indicated in the lower right corner of the IDE.

Attaching several thread dumps.

It doesn't seem to be GUI builder related. There is nothing from GUI builder in the attached thread dumps. It seems that the AWT thread is blocked in some java project stuff. Reassigning to Java/Project for evaluation.

Seems rather a problem in the FolderList (loaders).
Jardo, can you explain why the FolderList is waiting? I didn't find any activity in FolderList.
Thanks
Comment 6 Jiri Skrivanek 2010-01-04 02:47:05 UTC 
You are right it is not obvious what FolderList is waiting for. Cannot it be caused by some random race condition in JDK on Mac? Are you able to reproduce it? Could you try different JDK version?
Comment 7 Jaroslav Tulach 2010-04-07 19:34:40 UTC 
Strange, there is nothing the FolderChildren thread could wait for.
