This test runs unconditionally. `--memory-swappiness` is not supported in cgroups v2. Thus, the test will fail on a cgroups v2 system. You need to only run this test on a cgroups v1 system. Have a look at `test/lib/jdk/test/lib/containers/cgroup/MetricsTester.java` how could could detect this and only run on `cgroupv1` providers. ------------- PR: https://git.openjdk.java.net/jdk/pull/8285
