RFR: 8343838: Test EmptyDomainNotificationTest.java fails with ListenerNotFoundException [v2]

[Kevin Walls]

> Looks like EmptyDomainNotificationTest has been working by accident for nearly 20 years.
> Removing notifications when not specifying a domain part of the ObjectName has actually been failing, but calling removeNotificationListener() without a domain has not been sharing the Exception.
> 
> ServerNotifForwarder.removeNotificationListener DOES need to add a domain part to an ObjectName that does not have one.
> 
> ServerNotifForwarder.addNotificationListener was changed in JDK-6238731, which is what this test is testing.
> 
> There is a numeric ID, BUT it still calls removeNotificationListener(ObjectName name, Integer listenerID) it does matter that the ObjectName does not match.
> 
> Maybe the failure to record and throw the Exceptions was the reason it was thought the numeric ID made the domain unnecessary.
