JDK-8287073 - NPE from CgroupV2Subsystem.getInstance()
Description
While the issue of JDK-8287073 wasn't reproducible on a real system, we can synthetically reproduce this with a test that doesn't list the memory controller in /proc/cgroups file. That should be sufficient to provoke the NPE on an unpatched system.
Comments
Fix Request (OpenJDK 8u): Please approve this low-risk regression test for JDK-8287073. Patch does not apply clean. Minor test adaptations. Reviewed by Paul Hohensee. The code change in product code is a no-op in terms of functionality and should be low risk. Container tests continue to pass for me on x86_64 on cg1 and cg2. Also: The new regression test fails without the product code change in JDK-8287073 and passes after as expected.

Also: The new regression test fails without the product code change in JDK-8287073 and passes after as expected. For clean patch, depends on JDK-8287107 which is a good (low risk fix to have as well).
