Currently the jdk jtreg tests

jdk/internal/platform/docker/TestDockerCpuMetrics.java
jdk/internal/platform/docker/TestSystemMetrics.java

fail on Linux systems without
/sys/fs/cgroup/cpuset/cpuset.effective_cpus
and
/sys/fs/cgroup/cpuset/cpuset.effective_mems

Such systems exist , see also https://github.com/lxc/lxd/issues/1929 .
We see the error on a Linux s390x SLES12.1 , kernel is 3.12.49-11-default .

Error output :
