Hi @jerboaa, thanks a lot for the hints! The container tests were new to me at least.

Just out of curiosity, are the container tests run as part of the tier1 tests (`make test-tier1`)? I'm not sure if I'm looking at the right place, but I get the feeling this is defined in `test/hotspot/jtreg/TEST.groups`, and the answer is maybe "no" in that case.

> Please run container tests, which do some jcmd testing across containers (host system runs jcmd and containers have the JVMs): `test/hotspot/jtreg/containers` See [testing.md](https://github.com/openjdk/jdk/blob/master/doc/testing.md#docker-tests) as to how to run them. I'll give this PR a spin as well.

If I understand it correctly, this is the way to run them. Please correct me if I'm wrong.
