Urgh, I _so_ hate java.
Why does it have to pop up windows split between my screens, total fail.
In any case, I run it like:
java -jar SPECjvm2008.jar --benchmarkThreads 40
because I have 40 cpus (2 sockets * 10 cores/socket * 2 threads/core).
It seems to produce numbers, but then ends with a splat:

WTF a benchmark needs that crap is beyond me, but whatever, I have numbers.
I'll try and reproduce.
