This test was added for
CASSANDRA-13640. The comments seem to indicated this is only a problem on 3.0+, but the added test certainly seems to reproduce the problem on 2.1 and 2.2. Even if the issue does affect 2.1/2.2, it seems insufficiently critical for 2.1, so we need to limit the test to run on 2.2+ at the very least, possibly 3.0+ if we don't fix the cause on 2.2.
