| public boolean | hasTimedout()Returns if the receiver has timedout while trying to receive
notitifications from the server.
Timedout -- If a socket timeout happens while trying to connect
If the server is not reachable 3 times consequtively during thread loop.
If not able to connect when reinit is called.

| public boolean | reinit()Reinitialized the connection, if the connection is dropped.
This method is invoked from ClientNotificationManager every time the client
invokes a method on MBeanServerConnection.

|
| public void | run()The notification receiver thread loop.
This loop, if client has not called JMXConnector.close, will
try to read a notification message from the connection and notify
the ClientNotificationManager to dispatch the notification.
