/**
* Registers a <code>MessageListener</code> object.
* <p>
* The platform will notify this listener object when a message has been
* received to this <code>MessageConnection</code>.
* </p>
* <p>If the queue of this <code>MessageConnection</code> contains some
* incoming messages that the application haven't read before the call
* of this method, the newly registered listener will be notified
* immediately exactly once for each such message in the queue.
* </p>
* <p>There can be at most one listener object registered for
* a <code>MessageConnection</code> object at any given point in time.
* Setting a new listener will implicitly de-register the possibly
* previously set listener.
* </p>
* <p>Passing <code>null</code> as the parameter de-registers the currently
* registered listener, if any.
* </p>
* @param listener <code>MessageListener</code> object to be registered.
* If <code>null</code>,
* the possibly currently registered listener will be
* de-registered and will not receive notifications.
* @exception java.lang.SecurityException if the application does not
* have a permission to receive messages using the given port
* number
* @exception java.io.IOException if it is requested to register
* a listener on a client connection or if the connection
* has been closed
