Sorry in advance this isn't BSD specific, but i am frustrated to no end.  I
had a simple RMI program that binds to a port.  It works under 1.1, but not
1.2.  Could someone tell me why not?  It trips up on the Naming.rebind()
call.  I fussed with my securiy policy (finally have it working) and the url
format (complained it was malformed).  I am trying to connect to localhost.
I have rmiregistry running.

I whittle it down to only needing 2 small files.  Please help if you can,
i'm beating my head against a wall.

Here is the error message:
