Null is not a valid nil object reference. As others have pointed out,
you should use NotificationClient::_nil().

omniORB 3 used to be lenient and allow a null pointer; omniORB 4 is
not. What do people think?  Should it accept null?  If so, should it
emit a warning that it's wrong?

Cheers,

Duncan.
