--------------------------------------------

             Summary: sling:vanityPaths: observation listener should be started 
before initial scan on bundle activation to avoid missing changes
                 Key: SLING-2493
                 URL: https://issues.apache.org/jira/browse/SLING-2493
             Project: Sling
          Issue Type: Bug
          Components: JCR
    Affects Versions: JCR Resource 2.1.0
            Reporter: Alexander Klimetschek
            Priority: Minor


MapEntries [0] does first a scan in doInit() and then starts a thread for 
getting observation changes for sling:vanityPath nodes. Now if a observation 
event comes in between that, it gets lost - the old content was read in the 
initial scan and is cached. It looks like we had such a case while both bundle 
and content were updated "at the same time".

I think the observation listener for such cases should always be registered 
*before* the initial scan.
