Superclass of every connector server. A connector server is attached to an MBean server. It listens for client connection requests and creates a connection for each one.
A connector server is associated with an MBean server either by registering it in that MBean server, or by passing the MBean server to its constructor.
A connector server is inactive when created. It only starts listening for client connections when the
start method is called. A connector server stops listening for client connections when the
stop method is called or when the connector server is unregistered from its MBean server.
Stopping a connector server does not unregister it from its MBean server. A connector server once stopped cannot be restarted.
Each time a client connection is made or broken, a notification of class
JMXConnectionNotification is emitted.
