The test seems bogus as it can only run inside a docker environment. The NPE is caused by jdk.internal.platform.Metrics.systemMetrics() returning null. This is expected unless the JVM is running under docker. The test checks if docker is available on the machine, by running docker ps, builds a docker image, runs some tests in the docker image, but then calls Metrics.systemMetrics() outside of the created docker image and expects it to be non-null.

@JasonFengJ9 I expect this should be excluded everywhere it fails until it's working.

 * @summary Test JDK Metrics class when running inside docker container [1]

A docker-enabled machine label is required, this test along with other docker test friends can be excluded if the framework support is going to take a while.

jdk_container_jdk8 is a newly enabled test in dev.openjdk (see adoptium/aqa-tests#4147). dev.openjdk test build is also new and it sets to run in the docker environment. (i.e., LABEL_ADDITION=sw.tool.docker).

Since they are new, we do not yet have all the data on all versions/platforms. I do not see any valid Test_openjdk8_j9_dev.openjdk_aarch64_linux test builds at Adoptium. But the same test passed on s390 at Adoptium https://ci.adoptopenjdk.net/job/Test_openjdk8_j9_dev.openjdk_s390x_linux/7/

[llxia]

I also noticed the pipeline issue on platforms that do not have sw.tool.docker label (i.e., windows, mac, aix, etc). The pipeline issue is opened at adoptium/ci-jenkins-pipelines#568
