The recent Java update for OpenJDK, I believe, (~ Aug 14, 2008) breaks
some Java applications in window managers such as Awesome (and others).

>From the Awesome FAQ:
"Java applications which use the XToolkit/XAWT backend may draw grey windows only. The XToolkit/XAWT backend breaks ICCCM-compliance in recent JDK 1.5 and early JDK 1.6 versions, because it assumes a reparenting window manager. As a workaround you can use JDK 1.4 (which doesn´t contain the XToolkit/XAWT backend) or you can set the following environment variable (to use the older Motif backend instead): AWT_TOOLKIT=MToolkit"

Not sure how you would handle this but my application was working fine
before the update and then broke unceremoniously afterward -- switching
to another WM worked fine as did adding the AWT_TOOLKIT parameter.  It
just took a little research to find a fix.

I was switching back and forth between the sun-java package and the
openjdk -- I was able to get the parameter method to work using the sun
version, it didn't look like the OpenJDK version work with the
parameter.

Sun  Version (not sure this one ever worked right with Awesome):
Package: sun-java6-jre
Source: sun-java6
Version: 6-06-0ubuntu1

Old OpenJDK that worked:
6b09-0ubuntu2

New that seemed to break with the update:
6b11-2ubuntu2
