This is an issue with those classes which implement ObjectRenderer.  The
DefaultRenderer (which is called here) just do a

  return o.toString();

and it would be reasonable to return some dummy value if o was null.  Just
return "null" or null perhaps?

AttributesRenderer and ThreadGroupRenderer do an instanceof, UTObjectRenderer
just returns a parmeters, so this should be the only location which need
patching.
