I'm also tearing my hair out trying to find the problem. I'm using the standard Blackberry JRE 5.0.0 and using default java compliance compiler settings. It happens when I add the following class:

Also, I have some previous blackberry projects which keep installing on the emulator even though they've been deleted from the workspace and reappear everytime I launch. How do I delete them permanently?!
