[jdk8u-dev] RFR: 8292541: [Metrics] Reported memory limit may exceed physical machine memory

Tue Jan 3 11:53:32 UTC 2023

This is a backport of JDK-8292541 to jdk8u-dev as part of cgroups v2 support.

It's not clean: two separate fix ups were needed for 8u which are broken out in separate commits: add the new JNI method name to a mapfile; fully qualify the use of a method name in the test.

the edited test passes for me.
