Product Version: NetBeans IDE Dev (Build 201203260401)
Java: 1.7.0_03-icedtea; OpenJDK Client VM 22.0-b10
System: Linux version 3.2.0-2-686-pae running on i386; UTF-8; en_US (nb)
User directory: /home/paolo/.netbeans/dev
Cache directory: /run/netbeans

Yesterday I installed the latest nightly build. Today, on one file, whenever I press ctrl+z do undo NetBeans deadlocks and I have to kill the process.

I tried to do a stacktrace but jstack says:

root@saturn:/home/paolo# jstack -F 3972
Attaching to process ID 3972, please wait...

Not sure it's an issue of NetBeans or OpenJDK, but until now it never deadlocked so often.
