Fatal Error Handling
Hi Team,
What is the standard way in Mina of handing super fatal errors? i.e.
unrecoverable invalid internal state
Right now, I added an `assert` statement but that probably isn’t good
enough.

Look at my patch notes for Christoph’s dispose bug in JIRA DIRMINA-1076I
fixed the negative counter problem but want to add a critical check Incase
it ever reappears.

Uh oH...
The expected Session count should *never* become negative. If it's the
case, that needs to be fixed.
Do you have a clue about what can be the cause ?
Otherwise, everthing we would do to manage this situation would probably
be just a bad workaround...

There is a condition in the IoProcessor where the expected Session Count
turns negative. Basically the IoProcessor is now in a Fatal state. What
should happen?

Exception are trapped and probagated to the application through the
ExcetionCaught message, the session being closed in some specific case.
As we catch Exception, that covers RintimeException.
Errors aren't catched.
Do you have a bit more of context ?
