Yoko socket factory can give socket factory errors during server shutdown.

The Yoko ORB makes a self connection during ORB destroy() operations to shutdown the listener threads. If the ORB is using SSL connections AND the truststore and the keystore are not the same file, the SocketFactory will be unable to allocate the client SocketFactory because of the partial shutdown state. The SocketFactory needs to request the client factory at the same time the server factory is created to avoid this situation.
