This is a message from J-F.  I put this here to track this issue more easily:

Hi Niklas,

I suggested this some time ago. As Mina is asynchronous, this leads indeed to
state-based protocol handler.

It would be a great idea to develop code that could be reused.

The State pattern can help:
http://www.javaworld.com/javaworld/jw-08-1997/jw-08-stated_p.html.

Unfortunately, I don't know any open-source implementation of it.

Cheers,

J-F
