JDK 1.6.0_u2 on Ubuntu 7.04

I installed JDK 1.6.0_u2 on my Ubuntu Feisty 7.04 system using the self-extracting binary. I then proceeded to create symlinks in /usr/bin. After doing this, 'java -version' returns:

Java version"1.6.0"

Java(TM) SE Runtime Environment (build 1.6.0-b105)

Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)

so I know my links are working right.

I compiled a simple hello world program, and it compiled fine. I then ran it, and it ran fine.

After that, I ran an address book program I wrote. It opens the JFrame with the appropriate title, but without any contents! Ctrl-Q still closes the application, as it should, but there is nothing there. The same thing happens when I launch the P2P application FrostWire. I get a frame with no contents.

What could be wrong here? How do I fix this?

Thank you,

James Mazikowski
