java apps have blank screen

Do you run compiz/beryl by any chance?

There is a bug in some versions of java which results in swing-based
programs not rendering properly while using compiz/beryl.
I think it has been fixed in the latest (beta?) version of java.

I have the same problem running netbeans.

To get around it either turn off compiz/beryl when using the program, or
do as i do and run the program in a nested x-server.

I use Xephyr (you could also use xnest) with the icewm window manager to
do this.

$ sudo apt-get install xserver-xephyr icewm

Then use a script similar to: 

#! /bin/bash
# You could use Xnest instead of Xephyr here
Xephyr :2 -ac -screen 1024x768 &
icewm --display :2 &
export DISPLAY=:2
/path/to/executable &

Make the script executable and launch it.

Regards, 
Kyran.
