   Thank @bshashikant for catching the bug.  The ByteString from LogEntryProto 
should remain unchanged.  Only the message from client requests need to be 
changed.  Just have addressed this bug in 
   
   commit e6b25d101818031b64e61764aa6ce712250a1541 (HEAD -> trunk, 
origin/trunk, origin/HEAD)

       Fix a bug in ContainerStateMachine.
