Instantiates thisMBean instance with the data found for the MBean in the persistent store.

  Instantiates thisMBean instance with the data found for
the MBean in the persistent store. The data loaded could include
attribute and operation values.

This method should be called during construction or initialization of this instance,
and before the MBean is registered with the MBeanServer.
Throws:
- MBeanException - Wraps another exception or persistence is not supported
- RuntimeOperationsException - Wraps exceptions from the persistence mechanism
- InstanceNotFoundException - Could not find or load this MBean from persistent storage

  Captures the current state of this MBean instance and writes it out to the persistent store.

  Captures the current state of this MBean instance and writes it out to the persistent store. The state stored could include attribute and operation values. If one of these methods of persistence is not supported a "serviceNotFound" exception will be thrown.

Persistence policy from the MBean and attribute descriptor is used to guide execution of this method. The MBean should be stored if 'persistPolicy' field is:

  != "never" 
   = "always" 
   = "onTimer" and now > 'lastPersistTime' + 'persistPeriod'
   = "NoMoreOftenThan" and now > 'lastPersistTime' + 'persistPeriod'
   = "onUnregister"
 

 Do not store the MBean if 'persistPolicy' field is:
    = "never"
    = "onUpdate"
    = "onTimer" && now < 'lastPersistTime' + 'persistPeriod' 
 

Throws:
- MBeanException - Wraps another exception or persistence is not supported
- RuntimeOperationsException - Wraps exceptions from the persistence mechanism
- InstanceNotFoundException - Could not find/access the persistent store
