KAFKA-2455: Test Failure: kafka.consumer.MetricsTest > testMetricsLeak @guozhangwang I reproduced this; Every time this test failed, I found extra "type=DelayedFetchMetrics, name=ExpiresperSec, fetcherType=consumer/follower" inside Metrics.defaultRegistry().allMetrics().keySet(); that is because for "DelayedFetch", object DelayedFetchMetrics are loaded dynamically in function "onExpiration"; To fix, I explicitly load this object; Is it appropriate?
