I had been having this problem with OpenJDK 6
[openjdk-6-jre 6b27-1.12.6-1ubuntu0.12.04.2] 
and NetBeans 7.3.1. This problem first occurred
with the most recent upgrade of OpenJDK 6
in Ubuntu 12.04. The problem does not occur
after an upgrade to OpenJDK 7. See these bug 
reports for more details on this problem:

https://netbeans.org/bugzilla/show_bug.cgi?id=233381

I thought that I should apprise you of this 
situation so that you can insure that the same 
problem is not brought forward to OpenJDK 7.

Title:
  NetBeans, VisualVM, etc. broken with latest security release for 12.04

Status in “openjdk-6” package in Ubuntu:
  New

Bug description:
  The latest security update of OpenJDK 6 appears to have broken
  NetBeans and other NetBeans platform based applications such as
  VisualVM. It may break many other Swing applications - not tested.
  Manifests as UI issues, NPE's and lockups (eg. find usages dialog
  hangs NetBeans).  One stack trace shows EventQueue.isDispatchThread()
  returning false from within the dispatch thread.

  All is fine in current OpenJDK 7.  Looking at NetBeans on OpenJDK 6
  from VisualVM (running on 7!) shows multiple AWT event queues and
  sometimes deadlock between them. Same result is not seen when running
  NetBeans with OpenJDK 7.

  Running on 12.04 with OpenJDK-6-JRE 6b27-1.12.6-1ubuntu0.12.04.2
