I'm not sure, if I interpret your response correctly. Does the modified
run script succeed on your setup (base-hw on ARM)?
I have tried it on PC (linux, base-hw and base-nova) and it fails on all
kernels for me.

I'm using the same classes.tar. If the file is directly configured in
the <vfs> node of JAVA, execution succeeds. But if the tar is included
in the VFS-server and JAVA "mounts" the file system from it, the error
If I set the -verbose argument for JAVA, I see, that about 140 classes
are loaded successfully before the error occurs.
