Hi All,

Just noticed that the latest OpenJDK 6 security update on Ubuntu 12.04
has broken various UI things in the IDE, as well as Praxis LIVE and
Visual VM. This manifests as repaint issues, UI misconfiguration
(colours / borders), NPE's and occasional deadlock. Looking at a
platform app from VisualVM (running on 7 which seems OK) I can see
multiple event queue threads. One of the stack traces is an exception
thrown because EventQueue.isDispatchThread() is returning false from a
dispatch thread. I've not tried other Swing applications yet, so not
sure if it's only a problem with the platform.

Anyone else noticed similar issues with recent OpenJDK?

OpenJDK 7 seems fine (for now) - unfortunately that's not the default
Java version in Ubuntu 12.04 and I'd like to know things are working
with the default setup.

Best wishes,

Neil

Quick follow up for info - it's definitely not just me! At least it
doesn't seem to be only triggered by the platform.
