/**
 * {@link MethodHandler} that handles synchronous method invocations.
 *
 * 
 * This class mainly performs the following two tasks:
 * 

 *  Accepts Object[] that represents arguments for a Java method,
 *      and creates {@link JAXBMessage} that represents a request message.
 *  
Takes a {@link Message] that represents a response,
 *      and extracts the return value (and updates {@link Holder}s.)
 * 
 *
 * Creating {@link JAXBMessage}
 * 
 * At the construction time, we prepare {@link BodyBuilder} and {@link MessageFiller}s
 * that know how to move arguments into a {@link Message}.
 * Some arguments go to the payload, some go to headers, still others go to attachments.
