OK on updating the circleCI yaml in CASSANDRA-16604, as long as it is planned.
The new fix solved the issue that no tests are started. The test now runs -and
passes-.

(The front page showed a green check, but the job indicated that there were 18
failed tests)

> Remove test parallelism from ant build.xml in all branches
> ----------------------------------------------------------

> Key: CASSANDRA-16595
> URL: https://issues.apache.org/jira/browse/CASSANDRA-16595
> Project: Cassandra
> Issue Type: Task
> Components: Test/unit
> Reporter: Michael Semb Wever
> Assignee: Michael Semb Wever
> Priority: Normal
> Fix For: 2.2.20, 3.0.25, 3.11.11, 4.0-rc1, 4.0

> Time Spent: 20m
> Remaining Estimate: 0h

> Cassandra's build.xml supports parallel test runners. This functionality is
> available through {{`-Dtest.runners`}} and the {{`testparallel`}} ant macro.
> Having not been actively used and atrophied over time, it breaks a number of
> tests. The distributed in-jvm tests don't work at all with parallel runners
> (currently they need `-Dtest.runners=1` specified to work). And there are
> plenty of flakies, from where
> tests use fixed ports (StorageServiceServerTest), to byteman (eg
> BMUnitRunner), and around conf files on disk.
> This was raised on the dev ML, where the consensus was to remove it:
> https://lists.apache.org/thread.html/r1ca3c72b90fa6c57c1cb7dcd02a44221dcca991fe7392abd8c29fe95%40%3Cdev.cassandra.apache.org%3E
> The idea is to then replace ant test parallelism with docker container
> parallelism.
