> TestZKDelegationTokenSecretManager.testNodesLoadedAfterRestart() destroys the original DelegationTokenManager before creating a replacement,
> but does not destroy the replacement when the test finishes. Cleanup is also not guaranteed if initialization or an assertion fails.
> The teardown then closes ZooKeeper while the ExpiredTokenRemover thread may still be running.
> The thread can encounter ConnectionLossException while updating the shared key ID counter and call Runtime.exit(-1),
> terminating the Surefire JVM with exit code 255.
