JCR Server has concurrency issues on JcrWebdavServer.SessionCache internal HashMap caches
-----------------------------------------------------------------------------------------

                 Key: JCR-3027
                 URL: https://issues.apache.org/jira/browse/JCR-3027
             Project: Jackrabbit Content Repository
          Issue Type: Improvement
          Components: jackrabbit-jcr-server
    Affects Versions: 2.2.5
            Reporter: chad davis
             Fix For: 2.3.0


After doing the davex remoting performance work outlined in JCR-3026, the increased concurrency
on my jcr server exposed a lot of errors related to getting and putting from the JcrWebdavServer.SessionCache's
internal HashMap's.  This problem with HashMap's is a well known concurrency error and was
easily fixed by upgrading these maps to ConcurrentHashMaps.  Performance seems dramatically
better.
