I wasn't aware of this inconcistency. Do you know if its being fixed as part of the maintenance release?

hrmm... I don't trust the RI/javadocs to do the right thing all that much... in fact it seems they just mess up in a lot of places. So I'd prefer to go by the spec instead -- except in this case even the spec is inconsistent.

You might also try to post on JMX-INTEREST to find out what the real value should be, if you feel up to it.

its actually not just a registry specific problem... in general all listeners that are registered through MBean server should have their notification source fields set as the MBean's object name, where as the broadcasting MBean itself should be allowed to set the source as a reference to itself (this).
The RI handles this by intercepting all addNotificationListener calls and registering its own listener to whichever target the original invocation was meant for. When the MBean sends a notification, the server then receives it, replaces the 'this' reference with the corresponding object name and resends the notification to the original listener. That functionality is currently missing from our server.

juha Mar 14, 2002 12:24 PM (in response to adrian.brock)good, will you make sure we're using the correct notification type string? (if we aren't already)
