Description
When running Sling with Oak, the following warning is raised:
24.01.2014 10:28:44.905 *WARN* [pool-3-thread-1] org.apache.jackrabbit.oak.jcr.observation.ObservationManagerImpl Event listener ///*[11111b] is trying to access user information of event EventImpl{type=1, jcrPath='/OakRepositoryIT1390577324073', userID='admin', identifier='/OakRepositoryIT1390577324073', info={}, date=1390577324092, userData=null, external=false} without checking whether the event is external. java.lang.Exception: The event listener was registered here:

The reason for which can be found at http://jackrabbit.apache.org/oak/docs/differences.html#Observation
To avoid this warning, isExternal() should be checked before calling getUserID().
