No. I don't understand. I'm not sure of the current configuration, but it's strange
2 groups of developers. One network of broker where each component has a transport and a network connector with the same multicast group On components developed by the first group of developers : 2341 ObjectNames (I think it's OK when I count my consumers, queues, topics, advisory queues ...) 146 MBeanServerNotifications On components developed by the second group of developers : 72049 Object Names. 127956 MBeanServerNotification I think the most of ObjectNames are the subscription MBeans.
