I followed the tutorial to setup Eclipse and SVN, and downloaded the latest spark trunk 11779. Instead of using Install4j, I’m using izpack and lanuch4j. With these exceptions in the runtime, I cannot make the program “Launch on Startup” through Preferences -> Login settings.

I highly appreciate if anyone can tell what’s going on and help me fix this.
