public JID getJID() {
        return jid;
    }
Returns the JID that is going to receive the event notifications. This JID can be the
owner JID or a full JID if the owner wants to receive the notification at a particular
resource.<p>

Moreover, since subscriber and owner are separated it should be theoretically possible to
have a different owner JID (e.g. gato@server1.com) and a subscriber JID
(e.g. gato@server2.com). Note that letting this case to happen may open the pubsub service
to get spam or security problems. However, the pubsub service should avoid this case to
happen.

@return the JID that is going to receive the event notifications.
