> IdleTimeoutTicker maxReadIdle timeout is set to 2 seconds by default. When 2 seconds
interval expires, IdleTimeoutTicker initiate heartbeating.
> On AMQP 1.0 heartbeating is not implemented, as result, when client application does
not send any data,  IdleTimeoutTicker can cause an infinite spinning in IO thread due to resetting
selector interests which is set to read on selector wake-up. Selector interest continually
flips between OP_READ and 0.
> We can temporarily disable IdleTimeoutTicker by setting maxReadIdle to 0 until heartbeating
is implemented (QPID-6843) in order to work around the issue
