As you know CXF management provides a lots MBeans out of box. It works perfect if it run as stand alone.
If we deploy the CXF endpoints into container like Apache Karaf, we may hit the issue that Object is already registered. That is because we don't build up unique Object name for JMX to use.
To resolve this issue I suggest we add the "instance.id" on the ObjectName. As JMX supports to look up the object with a query string, I don't think this change will effect much on the user CXF management codes.
