/**
 * This unit test verifies:
 * 
 * 1. When a Connector creates a ServerInvoker and it has a reference to an MBeanServer, it will
 *    (a) register the ServerInvoker with the MBeanServer, and
 *    (b) it will pass the MBeanServer reference to the ServerInvoker
 *    
 * 2. When a Connector stops and it destroys a ServerInvoker, it will unregister the ServerInvoker
 *    with the MBeanServer.
 *
