SEVERE: UT000004: getResponseChannel() has already been called
by Karthick V.J.
Hi Undertow Devs,
I was getting the below error in my application. I created a sample application which throws the same error (Attached is the sample applicaiton) When I added the exchange.dispatch() statement at line 158, the problem resolves. Is it required to dispatch () every time the context is switched to a new thread. Am I doing it right?
Thank You - Karthick
