Created attachment 109057 [details] screenshot I have 2 larger projects opened in Netbeans, if I open another one, then netbeans are "Scanning projects" for some time and then the exception from the screenshot is thrown and Netbeans freeze, I can't do anything but xkill from command line to terminate them. I'll attach log from my user dir but I'm not sure, if it's related. I was able to reproduce it at least once. Product Version: NetBeans IDE 7.0.1 Dev (Build 201106122100) Java: 1.7.0; Java HotSpot(TM) Client VM 21.0-b16 System: Linux version 2.6.38-8-generic running on i386; UTF-8; en_US (nb)

Now it happened when I opened simple java file, the same exception.
Does this only happen on JDK 7, or JDK 6 as well?
I have tried to reproduce it several times on JDK 6 (with fresh user dir) but without success. However on JDK 7 it doesn't happen every time I open project or start IDE.
Please, provide a thread dump of the deadlock http://wiki.netbeans.org/GenerateThreadDump
Sorry, I forgot. I'll attach a thread dump as soon as possible
Unable to reproduce and no way to evaluate without the thread dump. Closing incomplete until the thread dump is provided.
