/**
 * If the handback object passed is an AgentImpl, updates the JMX client count
 *
 * @param notification JMXConnectionNotification for change in client connection status
 * @param handback An opaque object which helps the listener to associate information regarding
 *        the MBean emitter. This object is passed to the MBean during the addListener call and
 *        resent, without modification, to the listener. The MBean object should not use or modify
 *        the object. (NOTE: copied from javax.management.NotificationListener)
