OK, I probably need to re-run/debug Andrew's test to better understand what happens here, anyway: - yes, I would expect the same behavior with AS 4.2.x - so, considering the final changes for this issue, I understand in case of oneway invocations we would need to set the new property in the provided Client before calling the remoting code or set the unmarshaller (perhaps another one doing nothing) even if we call invokeOneway, right?
