ServiceControllerLifecycleCallback to unregister mbean?
Should the ServiceControllerLifecycleCallback be unregistering mbeans in uninstall()? It's doing the registration in install(), but I'm not seeing any unregister call (unless it's buried in the KernelController.)
I'm seeing problems with this in the EJB3 testsuite where I have an @JMX bean that gets deployed/undeployed in one test class and then deployed again in another.
The initial undeploy goes fine:

But then a subsequent deploy of the same -beans.xml fails because the old registration is still there:
