I have a quick and dirty patch, that essentially loads the resources dire=
ctly=20
from the jars in the classpath, without using URLs. I'm not sure about th=
e=20
design of the proper patch, though. I'll see what pocketlinux-kaffe has t=
o=20
offer for merge :)

It doesn't really help much. The next thing I get in GDB is a kaffe crash=
 in=20
xerces :( org.apache/xerces/StringPool.ensureCapacity(II)Z: the iaload ar=
ray=20
index check at pc=3D7 causes a SIGSEGV, since the array on stack is null.=
 That=20
doesn't seem to be picked up by the null check, though. Weird.
