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

             Summary: Tracker open to early which can cause a NPE.
                 Key: SLING-7507
                 URL: https://issues.apache.org/jira/browse/SLING-7507
             Project: Sling
          Issue Type: Bug
          Components: Commons
    Affects Versions: Commons Log 5.1.0
            Reporter: Karl Pauls
             Fix For: Commons Log 5.1.2


The FilterTracker and TurboFilterTracker service tracker are opened in the constructor of the LogbackManager at a time when it isn't fully configured yet. That can lead to an NPE if there is a service found right away.
