While I've never actually used Mina's UDP yet, you need to keep in mind that UDP doesn't use connections. I believe the Datagram connector simply does nothing when you "connect" with it; no traffic is sent to the server. So, a UDP session will always be "connected" and a connect attempt will always be successful. Or at least, that's what I assume.
If you need to know whether you've successfully connected to a server, use TCP instead (NioSocketConnector).
