         56822: ALF-20361: Not possible to edit MS Office document via CIFS if it was edited via CIFS and then new version was uploaded
         - Corrected LockServiceImpl.getLockState so that it handles the case when a "non-lock" appears in the lock store following a rollback
         - Added check for existence of NodeRef in LockServiceImpl.getLockState before testing for the Lockable aspect
