>> This backport is one commit on top of pr/121. It does not apply clean after path unshuffling: some of the patch contexts around `MetricsMemoryTester.java`,  `MetricsTesterCgroupV1.java` and  `MetricsTesterCgroupV2.java` differ due to changes made in pr/121 to adjust for jdk8u-dev support (replacing `Arrays.compare` with `Arrays.equals`)

>> I'll report back testing results to this PR, I have to untangle them a bit first.
