Description

In Oak, the Consolidated Listener Stats MBean provides an overview of all listeners, including the name of the class. When used in Sling (and esp with SLING-6056) a new bunch of listeners is added, namely ResourceChangeListeners that will get mapped 1:1 to an oak listener/backgroundobserver. Currently though, the consolidated listeners mbean only shows the getClass().getName() - which in the case of a ResourceChangeListener doesn't help much, as the 'real' listener hides 2 steps behind either a JcrResourceListener or a OakResourceListener. So it wouldn't be possible to tell from a list of such listeners what really is behind.

Therefore suggesting to introduce a

    /** toString of the event listener */
    String getToString();

that then can be used by the ConsolidatedListenerMBeanImpl
