hmm. That sure looks a little bit weird, but I think it's ok.
And it definitely worked before we implemented the AppClassLoader
stuff....

It finally turned out to be a bug in java.net.URLClassLoader:
java.net.URLClassLoader.findClass() tries to find the .class
file using findResource(). PlatformClassLoader.findResource()
however delegates the call to findResource() to the xmlClassLoader
which succeeds in loading that resource, which in turn causes
the PlatformClassLoader to succeed in loading that class :( 
Fix is in CVS.

Next problem is a failure in System.arraycopy().... 

Thanks,
Helmer
