Thanks to tlayton_at_work in the Ubuntu Forums, there is a handy little work around for the Sun Java 6 issues in Hardy.
$ echo "export LIBXCB_ALLOW_SLOPPY_LOCK=true" >> ~/.bash_profile
Works like a champ, and now I am back to creating GUIs with Netbeans, and running my code in Eclipse. Thanks tlayton_at_work, you rock!
