Chia-Ping Tsai commented on KAFKA-18770:
----------------------------------------
The root cause of the test failures lies in the failure to close the
{{ReplicaManager}} within the
{{testDelayedShareFetchPurgatoryOperationExpiration}} method. This omission
results in an unreleased thread from the purgatory, leading to subsequent
integration test failures due to thread leaks.
> Fix flaky initializationError in ReplicationQuotasTest/RequestQuotaTest
