I've been merging latest GNU CP CVS into SableVM's "staging" branch.
Previously we used gnu.java.lang.SystemClassLoader, but after reading
"Java Security" I realized we should be using URLClassLoader! (and was
going to look into fixing that anyway) So I am quite happy with the
changes in ClassLoader, which make us use the proper URLClassLoader.

I like it, altough I only ran simple HelloWorld, because running
a program that requires i.e. ressources (loaded from .jar) gives me:

So, if you have a fix for that, could you please post it or check in?
Robilad told me he has the same kind of issue with Kaffe as we have with
SableVM after the merge.

Thanks,
