Review Comment:
If you ran the test Long enough before it would probably also fail.
all I did was to move the connectionFailure to the correct thread.

> Failure Detection has a possibility to a race condition with the processing
> of the client packets (or frames in the case of AMQP).
> This is because Netty detects the failure and removes the connection objects
> while the packets are still processing things.
> I was not able to reproduce this particular issue, but I have seen a case
> from a memory dump where the consumer was created while the connection was
> already dropped, leaving the consumer isolated without any communication with
> clients.
> That particular case I could see a possibility because of these races.
> I am adding tests to exercise connection failure in stress and I was able to
> reproduce other issues.
