      Description

      I think there are two bugs in EmbedConnection.clearLOBMapping():

      1) It checks if lobHashMap is non-null, but it should have checked rootConnection.lobHashMap.
      2) It calls getlobHMObj().clear() regardless of whether there is a HashMap. This creates a HashMap object even though it's not needed, and all the subsequent transactions on that connection have to perform cleanup on that object.
