JBoss will crash otherwise. It still doesn;t load until ZipFile.close() 
is commented out completely, but then, with JAVA_OPTS set to "-Xss 256k 
-Xmx 256M -Dbuild.compiler=kjc" the management console works well enough 
for a JBoss 3.2.3 screenshot

numerous weird exceptions.

That was a side effect of trying to get JBoss to run again, as I didn;t 
like the PrimordialClassLoader opening and closing the same Zip files 
all the time, so I cached them in a Hashtable. I hope there is a 
positive effect on performance wrt class loading, but I haven't tried to 
measure it.
