The class javax.management.monitor.MonitorNotification has no visible constructors. Instance of this class are constructed by the Monitor Service only. Adding a public constructor would be desirable for a couple of reasons:
* It would allow reimplementations of the Monitor Service outside the package javax.management.monitor.
* It would simplify the code of connectors (e.g. XML-based) that need to deserialize an instance of MonitorNotification. (Connectors such as the RMI connector that are based on Java serialization are not affected.)
