Implicit implementation of abstract decorator method with at least one parameter is missing
-------------------------------------------------------------------------------------------

                 Key: WELD-1021
                 URL: https://issues.jboss.org/browse/WELD-1021
             Project: Weld
          Issue Type: Bug
            Reporter: Martin Kouba


If an abstract decorator declares abstract method and this method is also declared on decorated type, the container should provide an implicit implementation of this method that calls the method on the delegate. However if the method has at least one parameter implementation is missing.
