public class AttributeChangeNotification extends Notification
It's up to the MBean owning the attribute of interest to create and send
attribute change notifications when the attribute change occurs.
So the NotificationBroadcaster interface has to be implemented
by any MBean for which an attribute change is of interest.
Example:
If an MBean called myMbean needs to notify registered listeners
when its attribute:
String myString
myMbean creates and emits the following notification:
new AttributeChangeNotification(myMbean, sequenceNumber, timeStamp, msg,
"myString", "String", oldValue, newValue);
