It turns out the problem with NetbBeans 6.0 not rendering well when desktop effects are enabled in Fedora 8 has been solved at the JDK level. Just upgrade to JDK 6 update 4 from Sun. Now my NetBeans will enjoy being wobbled about.
Oh and i just discovered JavaDB (or more popularly Derby) is bundled with JDK 6. Didn’t quite notice its existence. And with the latest JDK it comes with documentation on how to use it in your apps. This is good for simple applications that need to bundle some small database to work with. Congrats to Sun.
