        Description

        With JDK-8253435 and JDK-8252359 some more bugs got discovered in the container detection code: cgroups v1 vs. cgroups v2. For those fixes, regression tests got added for the hotspot code.

        Also, JDK-8217766 got created without a regression test which now should be possible so as to prevent bugs like JDK-8254854.

        We should have proper tests so this doesn't regress some weird corner case in some future refactoring.
