[undertow-dev] Checking if an exchange has been dispatched

[Stuart Douglas]

isDispatched() will only return true if a dispatch is going to happen 
when the call stack returns.

So when you are in the IO thread and call the dispatch() method from 
that point on isDispatched() will be true, however as soon as the call 
stack returns and the dispatch happens this goes back to false (as it is 
possible to dispatch multiple times).

The check you are probably looking for is exchange.isInIoThread(), which 
will return true if the current thread is the IO thread.
