I would like to backport 8200109, as it could result intermittent
assertion failures of runtime/NMT/JcmdDetailDiff.java test.

The fix has pushed to JDK13.
JDK13 Bug:    https://bugs.openjdk.java.net/browse/JDK-8200109
JDK13 Webrev: http://cr.openjdk.java.net/~zgu/JDK-8200109/webrev.00/
Code review: https://mail.openjdk.java.net/pipermail/hotspot-runtime-de

JDK13 patch did not apply cleanly, there are minor conflicts in
memReporter.cpp and whitebox.java. There are also changes in new test,
due to test library changes between 8 and 13.

JDK8u Webrev: http://cr.openjdk.java.net/~zgu/JDK-8200109-8u/webrev.00/

  runtime/NMT on Linux x64 (fastdebug and release)
