             Summary: Fail build or warn when closeable reference is not closed in tests
                 Key: CASSANDRA-17400
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-17400
             Project: Cassandra
          Issue Type: Task
            Reporter: Paulo Motta


I came across a recent test stuck issue which was caused by an {{Autocloseable}} object not being closed properly, leaking some references and ultimately causing a deadlock.

To prevent similar issues in the future we should add a check that fail or warn when references are not closed during tests.

If such check already exists we should look into fixing violations.
