[jira] [Created] (CASSANDRA-15171) In-JVM dtests leak file handles after closing cluster

Jon Meredith created CASSANDRA-15171:
----------------------------------------

             Summary:  In-JVM dtests leak file handles after closing cluster
                 Key: CASSANDRA-15171
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-15171
             Project: Cassandra
          Issue Type: Bug
          Components: Test/dtest
            Reporter: Jon Meredith


From the work in CASSANDRA-15170, reviewing the output from lsof shows that file descriptors from closed clusters are still open after all instance objects and the instance class loader have been garbage collected.

To run sustained fuzz/property based testing, file handle leaks need to be minimized.

Reproduce by running ResourceLeakTest.looperTest included as part of CASSANDRA-15170 and look at `build/test/*-lsof-final.txt`
