Description

When the client gets back a response, it throws a "JAXBBlockImpl block object is already consumed" exception. Reason is in RPCLitMethodMarshaller aorund line 348, we use MethodMarshallerUtils.getReturnElement to get back the return string. but then line 368, we call MethodMarshallerUtils.getPDElements and try to unmarshal the other 2 holders. So we get an exception saying that the block is already consumed.

thanks,
dims
