> The JmxWhiteboardSupport class maintains an internal structure to keep track of MBean services registered with MBean servers. This currently is a map from MBeanHolder onto itself using special crafted MBeanHolder.equals/hashCode to support retireval on MBean unregistration.
> It would probably be better use an IdentityHashMap<Object,MBeanHolder> indexed by the service object which is easily accessible and does place any special requirements on the service object.
> Consequently the hashCode and equals methods of the MBeanHolder class can be removed.
