      When I use non-existent attribute name for 'list-add' operation, I get following NPE in server.log:

      Yeah - I understand that it is my fault that I provided bad command. But still, server should not respond with NPE. Ideally it should told me that provided list attribute does not exist for particular element and should finish operation with error.
