This requires something in the VFS, my suggestion was to add
VFSUtils.getRealURL(vfsFile);

This is also in the VFS, in the url handlers.

This is in the VFSClassLoaderPolicy and it is a simple boolean
to control which codeSourceURL to use.
It also requires adding root.toURL().openConnection().getPermission()
to the permissions of the protection domain (assuming it is not the 
default AllPermission like it currently is now for vfs urls).
