Hello, Looking into TCPSampler code, I think there is something that's not very clean.
Currently if TCPClient implementation is not correctly setup, we end up with a null protocolHandler. In this case, every sample will lead to an error 500 with "Protocol handler not found" message. I think it would be cleaner in this case to throw a JMeterStopTestException as it is most probably a configuration exception. Currently if a test lasts 2 hours, test runs until it's finished, with change it stop immediately Thoughts ? -- Cordialement. Philippe Mouawad.
