[8u] RFR: 8250984: Memory Docker tests fail on some Linux kernels w/o cgroupv1 swap limit capabilities

[Hohensee, Paul]

Nit: the original patch for TestMemoryAwareness.java has a blank line between the two try-catch blocks that isn't present in your patch.

Otherwise, lgtm, and no need for another webrev.

Thanks,
Paul

    Hi,

    Please review this container fix for OpenJDK 8u. It fixes an issue for
    systems which don't have swap accounting turned on. This is an Oracle
    JDK parity fix too. The differences to the JDK 11 patch are minor:

     * Split of the patches between hotspot and jdk repositories in JDK 8
     * New OutputAnalyzer import in TestMemoryAwareness.java. Introduced
       with JDK-8229182 in JDK 11 currently not slated for backport in 8.

    webrev: https://cr.openjdk.java.net/~sgehwolf/webrevs/JDK-8250984/jdk8/01/

    Testing: Container tests on Linux x86_64 cgroup v1 with swappaccount=0.
    Fails before, passes after.

    Thoughts?

    Thanks,
    Severin
