Ismael Juma commented on KAFKA-5289:
------------------------------------
[~xuzq_zander], because we don't to delay the response while the idle threads
are being shutdown.
[~markTC], both questions are important, actually. Yes, `KafkaApis` should
protect itself against exceptions if it performs an operation after the
response is sent, but there could also have been a bug in
`shutdownIdleFetcherThreads()` (and hence the question).
