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"

= "never" = "onUpdate" = "onTimer" && now < 'lastPersistTime' + 'persistPeriod'
