[jira] [Created] (KAFKA-14896) TransactionsBounceTest causes a thread leak

Justine Olshan created KAFKA-14896:
--------------------------------------

             Summary: TransactionsBounceTest causes a thread leak
                 Key: KAFKA-14896
                 URL: https://issues.apache.org/jira/browse/KAFKA-14896
             Project: Kafka
          Issue Type: Bug
            Reporter: Justine Olshan
            Assignee: Justine Olshan


On several PR builds I see a test fail with ["Producer closed forcefully" |https://ci-builds.apache.org/job/Kafka/job/kafka-pr/job/PR-13391/21/testReport/junit/kafka.api/TransactionsBounceTest/Build___JDK_8_and_Scala_2_12___testWithGroupId__/]
and then many other tests fail with initialization errors due to [controller-event-thread,daemon-broker-bouncer-EventThread|https://ci-builds.apache.org/job/Kafka/job/kafka-pr/job/PR-13391/21/testReport/junit/kafka.api/TransactionsBounceTest/Build___JDK_8_and_Scala_2_12___executionError/]

In TransactionsBounceTest.testBrokerFailure, we create this thread to bounce the brokers. There is a finally block to shut it down but it seems to not be working. We should shut it down correctly.

Examples of failures:
