I have moved this thread to the Java forum with the hopes that the experts there will be able to provide you with more help than those in the Linux forum.

[JosAH]

Have you installed Sun's jdk and jre? I suspect that gnu's implementation doesn't
supply the character encoding it was looking for.

kind regards,

Jos

I believe you are right .

Given that humongous stack trace it's the only conclusion I can come up with.
Let's wait for the OP and see.

If anyone is under stress right now I suggest they take time to crack this.

Nah, I'm not under stress and I'm way too lazy to stare at an almost random
sequence of bits that can be almost anything.
