>From the error message, it looks like you are using gcj instead of the
VM provided by Sun. The first thing I would try is to install the sun
JVM, then try to run the program with that. This guide:

https://help.ubuntu.com/community/Java

will help with the process. Just make sure that, after you install the
sun JVM, run:

$ sudo update-alternatives --config java

to set the sun JVM as the system default JVM.

If the program still doesn't work with the sun JVM, then something
deeper is amiss.
