Thanks for looking through these changes.  Thanks @AlanBateman  for answering the question about remaining uses of protection domain.  When we create an instance of java.lang.Class, the VM stores the protection domain given in resolve_from_stream.  I may have already said this somewhere.  So we need to pass it through that path.
