Description everflux 2012-11-03 09:08:50 UTC 
[ BUILD # : 201211020750 ]
[ JDK VERSION : 1.7.9 ]

When testing the Netbeans 7.3 beta 2 build my X session was blocked and
Netbeans stopped working.

Happened when Netbeans was just started and I clicked on the menu in order to
obtain the build number.
I was able to obtain a threaddump from the console with the jcmd cli tool - I
am not sure if this could be a JDK problem instead of Netbeans/RCP. (The locks
seem to be owned by AWT threads?)

I had to kill the JVM with -9 from the console in order to be able to use my X session again. This was really frightening.

Please switch to promoted builds of 7u10, where this JDK bug is fixed, available at
http://jdk7.java.net/download.html
