8228658: test GetTotalSafepointTime.java fails on fast Linux machines with Total safepoint time 0 ms

[sendaoYan]

Hi all,
We observerd the test sun/management/HotspotRuntimeMBean/GetTotalSafepointTime.java intermittent fails on jdk8u-dev. The failure phenomenon samt to JDK-8228658. So I want to backport this PR from jdk11u-dev to jdk8u-dev.

Only the copyright year backported not cleanly, the copyright year modified by JDK-6719955 and JDK-6943119 in jdk8u-dev. Other parts are backport cleanly.

The change has been verified locally, make the test more robustness, test fix only, no risk.
