The CommonClient calls the handler chain before unbindResponseMessage(). This is correct.
However, XOP inline depends on ParameterMetaData.isXOP().
The ParameterMetaData is not known until unbindResponseMessage()

// Get the return object
Object retObj = null;
if (oneway == false)

{ // Call the response handlers callResponseHandlerChain(portName); // unbind the return values SOAPMessage resMessage = msgContext.getMessage(); binding.unbindResponseMessage(opMetaData, resMessage, epInv, unboundHeaders); retObj = syncOutputParams(inputParams, epInv); }
