gaurav-narula opened a new pull request, #15996: URL: https://github.com/apache/kafka/pull/15996
An exception thrown while closing the client instances in `IntegrationTestHarness::tearDown` may result in `KafkaServerTestHarness::tearDown` not being invoked. This would result in thread leaks of the broker and controller threads spawned in the failing test. An example of this is the [CI run](https://ci-builds.apache.org/blue/organizations/jenkins/Kafka%2Fkafka-pr/detail/PR-15994/1/tests) for #15994 where `Build / JDK 8 and Scala 2.12 / testCoordinatorFailover(String, String).quorum=kraft+kip848.groupProtocol=consumer – kafka.api.PlaintextConsumerTest` failing results in `consumers.foreach(_.close(Duration.ZERO))` in `IntegrationTestHarness::tearDown` throwing an exception. A side effect of this is it poisons Gradle test runner JVM and prevents tests in other unrelated classes from executing as `@BeforeAll` check in QuorumTestHarness would cause them to fail immediately. This PR encloses the client closure in try-finally to ensure `KafkaServerTestHarness::tearDown` is always invoked. ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
