    Description

      When a sliding rule is defined of Steam mode and Async Mode of the droolsEventprocessor. Rule is activated but the handling of the results fails with a NPE.
      NPE traced back to the Node object responsible for handling the forward of the serialized object as the passed in _container object is null;
