PoAn Yang commented on KAFKA-16792:
-----------------------------------
The {{ApplicationEventProcessor#process(PollEvent)}} only reset timer for some
request managers. Even if we use {{ApplicationEventHandler#addAndGet}}, we
still can't guarantee {{runOnce}} is executed. We may need
{{ConsumerNetworkThread}} to send a {{BackgroundEvent}} to make sure the
{{runOnce}} is happened. However, this ㄇapproach may make the process more
complex.
> Enable consumer unit tests that fail to fetch offsets only for new consumer
> with poll(0)
