Category: JBossMX Group: v3.2 Status: Open Resolution: None Priority: 5 Submitted By: Jeff Haynie (jhaynie) Assigned to: Nobody/Anonymous (nobody) Summary: Problem with source of JMX Notifications Initial Comment: According to the JMX spec, the source of a Notification must be of type ObjectName. At line 420 in ServerImpl: Notification msg = new Notification (START_NOTIFICATION_TYPE, this, 1); should be changed to: Notification msg = new Notification (START_NOTIFICATION_TYPE, ServerImplMBean.OBJECT_NAME, 1); We should also update JMX to check this (although I thought it did before - maybe its happening at the at a higher level in the BasicMBeanRegistry). The problem is that the ListenerRegistration in the NotificationBroadcasterSupport.sendNotification() will evaluate the NotificationFilter before being dispatched up to the listener. The listener is being wrapped at a higher level by the mbean server using the NotificationListenerProxy which sets the source - but this happens after the filter is applied -- which causes problems if you're checking the ObjectName in the filter. An easy enough fix for this particular problem is just to do above. However, I'm worried we'll still see this in other places. Another thought is to wrap the MBeanServerListenerRegistration (which creates NotificationListenerProxy) and pass in a proxy to the filter, such that it will set the appropriate source using the MBeanServerListenerRegistration and then delegate to the appropriate filter. The other thing is to enforce in our Notification implementation ObjectName in setSource and the constructor -- which according to the JMX spec we're suppose to throw an IllegalArgumentException. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=376685&aid=871649&group_id=22866 ------------------------------------------------------- This SF.net email is sponsored by: IBM Linux Tutorials.
