org.objectweb.joram.mom.messages.Message
The Message class actually provides the transport facility for the data exchanged during MOM operations.
A message content is always wrapped as a bytes array, it is characterized by properties and "header" fields.

    receiving = in.readBoolean();
    messages = (List) in.readObject();
    deliveredMsgs = (Map) in.readObject();


    for (int i = 0; i < messages.size(); i++) {
      Message message = (Message) messages.get(i);
      // Persisting the message.
      setMsgTxName(message);
      message.save();
    }
