Doug Cutting updated AVRO-687:
------------------------------

    Attachment: AVRO-687.patch

Here's a patch for this.  It still needs tests.

When a server has not been previously contacted then this constructs a bogus request to force a handshake.  This may result in an error stack trace in the server's log but should otherwise work.  Perhaps we should designate a special message name that's otherwise illegal for this purpose.  Responder could then avoid logging an error in this case.

> It would be useful for RPC-based applications to inspect the remote protocol.  A client might this to, e.g., detect the presence of a method that's recently been added to a protocol.
