[kaffe] I want to use java TV API. Am I able to use kaffe vm?

[Rafael Teixeira]

As Dalibor opened up to have thoughts on XScale VMs let me say that
I'm having better luck with JamVM (interpreted-only) on my IXP425
board, at least the show-stopping thread-problems could be diagnosed
and amended on JamVM. If I had some time to spare I would try to see
if Kaffe problems may have a similar solution, but currently I have
none.

Some other bits I had trouble were located in the Java class libraries
and  I've sent upstream to Gnu Classpath, which benefits both VMs.
