[Apiman-user] duplicate response on Connetor timeout

[Marc Savy]

With regards to debugging:

I assume you are using the Servlet/WAR gateway with WildFly?

If so, I suggest you consult the WF debugging guides -- but, in short, you
can start up the application server with --debug and connect to it remotely
from  your debugger (e.g. Eclipse, IntelliJ, etc).
