Another problem I'm seeing is that many beans implement MBeanRegistration, but those callbacks aren't getting invoked. I think this is because the object registered with the MBeanServer is not the bean itself but rather a StandardMBean created in JMXIntroduction. That object doesn't implement MBeanRegistration. With the beans I'm working with, it's actually not necessary to wrap them in a StandardMBean object before registering them. They are all already compliant standard mbeans of the X implements XMBean variety. I'm going to play a bit and see if there's any issue with registering the beans directly.
