69946: Merged V4.2-BUG-FIX (4.2.3) to HEAD-BUG-FIX (4.3/Cloud)
      69860: MNT-11371: Alfresco unable to bootstrap due to LockTryExceptions following an upgrade from 3.4.8 -> 3.4.13 -> 4.0.2 to either 4.1.8 or 4.2.1
      Merged 4.1.N to V4.2.N (4.2.3)
         69848: MNT-11371: Alfresco unable to bootstrap due to LockTryExceptions following an upgrade from 3.4.8 -> 3.4.13 -> 4.0.2 to either 4.1.8 or 4.2.1
           Ability to configure try lock timeout for several different contexts has been implemented. New configuration for every context has been added:
           - system.lockTryTimeout=100
           - system.lockTryTimeout.DictionaryDAOImpl=2000
           - system.lockTryTimeout.MessageServiceImpl=${system.lockTryTimeout}
            - system.lockTryTimeout.PolicyComponentImpl=${system.lockTryTimeout}
           'LockHelper.tryLock()' has been modified to accept additional string 'useCase' parameter. Parameter is used for throwing exceptions with contextual messages when lock is not acquired
         69858: MNT-11371: Alfresco unable to bootstrap due to LockTryExceptions following an upgrade from 3.4.8 -> 3.4.13 -> 4.0.2 to either 4.1.8 or 4.2.1
           Additional boolean parameter 'haveWriteLock' has been added to 'MessageServiceImpl.getResourceBundleBaseNames()' method. It serves to avoid unlocking external write locks. The method still assumes that read lock is acquired if 'haveWriteLock=false'. Read lock will be upgraded to write lock only if 'haveWriteLock' parameter is equal to false
