Hi Ryan,

I've got past the JAR problem by using the java.util.zip implementation 
from GNU Classpath, instead of Kaffe's. It seems that Kaffe's jar 
reading code has a few problems, unfortunately. It would be interesting 
to try to merge in the java.util.zip code from gcj, which also uses 
zlib, like Kaffe.

Unfortunately, even with that fix, I got stuck on a GNU Classpath AWT 
bug. Mark Wielaard is working on a fix for that one. I'll try to merge 
more of java.util.zip with GNU Classpath meanwhile.
