> When ChangeProcessor.stopAndWait fails (returns false) the [ObservationManager issues
a log.warn|https://github.com/apache/jackrabbit-oak/blob/be59ea9a098279fd243f83ff0ecbcb8fa71249db/oak-jcr/src/main/java/org/apache/jackrabbit/oak/jcr/observation/ObservationManagerImpl.java#L457]
resulting in something like this:
> {noformat}
> 20.02.2017 16:40:05.773 *WARN* [FelixStartLevel] org.apache.jackrabbit.oak.jcr.observation.ObservationManagerImpl
Timed out waiting for change processor to stop after 1000 milliseconds. Falling back to asynchronous
stop on ChangeProcessor [listenerId=56, tracker=//*[11111b]@org.apache.sling.jcr.resource.internal.JcrResourceListener,
contentSession=session-1181, eventCount=org.apache.jackrabbit.oak.plugins.metric.CompositeStats@3da35e6e,
eventDuration=org.apache.jackrabbit.oak.plugins.metric.CompositeStats@308ca75f, commitRateLimiter=null,
running=false]
> {noformat}
> Unfortunately - in case of the Sling JcrResourceListener - you can't know which actual
{{ResourceChangeListener}} is hiding behind it.
> The above log.warn should be improved to also show the {{getToString()}} of the listener
which provides more details including the actual ResourceChangeListener.
