/**
 * {@link MethodHandler} that handles synchronous method invocations.
 *
 * 

* This class mainly performs the following two tasks: *

    *
  1. Accepts Object[] that represents arguments for a Java method, * and creates {@link JAXBMessage} that represents a request message. *
  2. Takes a {@link Message] that represents a response, * and extracts the return value (and updates {@link Holder}s.) *
* *

Creating {@link JAXBMessage}

*
