Flaky IT: ITKafkaIndexingServiceTransactionalParallelizedTest.testKafkaIndexDataWithStartStopSupervisor

[paul-rogers]

The IT ITKafkaIndexingServiceTransactionalParallelizedTest.testKafkaIndexDataWithStartStopSupervisor failed in this build:

The usual caveats apply. The PR in question is related to the Avatica JDBC driver and changed no files related to supervisors. The same test had passed on previous builds of this branch. Hence, it seems this test failure is random.
