Summary: DelegationTokenEndToEndAuthorizationWithOwnerTest leaks
threads
Key: KAFKA-15977
URL: https://issues.apache.org/jira/browse/KAFKA-15977
Project: Kafka
Issue Type: Bug
Reporter: Lucas Brutschy
[https://ci-builds.apache.org/blue/rest/organizations/jenkins/pipelines/Kafka/pipelines/kafka-pr/branches/PR-14878/runs/8/nodes/11/steps/90/log/?start=0]
I had an unrelated PR fail with the following thread leak:
```
Gradle Test Run :core:test > Gradle Test Executor 95 >
DelegationTokenEndToEndAuthorizationWithOwnerTest > executionError STARTED
kafka.api.DelegationTokenEndToEndAuthorizationWithOwnerTest.executionError
failed, log available in
/home/jenkins/workspace/Kafka_kafka-pr_PR-14878/core/build/reports/testOutput/kafka.api.DelegationTokenEndToEndAuthorizationWithOwnerTest.executionError.test.stdout
Gradle Test Run :core:test > Gradle Test Executor 95 >
DelegationTokenEndToEndAuthorizationWithOwnerTest > executionError FAILED
org.opentest4j.AssertionFailedError: Found 1 unexpected threads during
@AfterAll: `kafka-admin-client-thread | adminclient-483` ==> expected: <true>
but was: <false>
```
All the following tests on that error fail with initialization errors, because
the admin client thread is never closed.
This is preceded by the following test failure:
```
Gradle Test Run :core:test > Gradle Test Executor 95 >
DelegationTokenEndToEndAuthorizationWithOwnerTest >
testNoDescribeProduceOrConsumeWithoutTopicDescribeAcl(String, boolean) > [1]
quorum=kraft, isIdempotenceEnabled=true FAILED
