Thanks, this helped a lot.

The appended is a small test showing what goes wrong.

This works with the bytecode interpreter because URLClassLoader
defines the package for classes it defines.  However, compiled classes
don't have a Package defined for them, causing the package code in
Proxy to fail.

The simplest fix may be to change Proxy to compute the package name
itself, from the class name, rather than to go through the Package.
This won't fix the appended, but there's no guarantee that
getPackage() will return a non-null result.

I'm still looking at this, though.  Maybe I'll fix the vm class
loader instead.

package qt;
public class foo
{
  public interface z { };
  public static void main(String[] args)
  {
    System.out.println(z.class.getPackage().getName());
  }
}
