Description svanimpe 2012-11-10 13:22:10 UTC

Netbeans 7.3 Beta 2 simply freezes when I start it up. The UI shows up but it freezes immediately. I get the spinning beachball and have to force-quit.

I am using OSX 10.8.2 and JDK 7u9.

I was previously using 7.2 with no problems.
I have completely removed 7.2 (including settings, application support files, etc) before installing 7.3.

Can you make a thread-dump and attach it here? http://wiki.netbeans.org/GenerateThreadDump

Comment 2 svanimpe 2012-11-10 15:16:19 UTC

The following is printed when I press Ctrl-\ when starting NetBeans from a Terminal. Is this the information you wanted ?
