/**
* A {@link ReadHandler} for the new-client. It passes the ByteBuffer to the ClientMessageReadHandler. For each
* constructed ClientMessage, the {@link #handleMessage(ClientMessage)} is called; which passes the message
* to the {@link IOService#handleClientMessage(ClientMessage, Connection)}.
*
* Probably the design can be simplified if the IOService would expose a method getMessageHandler; so we
* don't need to let the ClientReadHandler act like the MessageHandler, but directly send to the right
* data-structure.
