8381270: TestGCPhaseConcurrent.java#Z intermittent fails OOME

[sendaoYan]

Hi all,

This backport will fix the test bug which cause test intermittent OOME fails, jdk21u-dev lack JDK-8318098(Update jfr tests to replace keyword jfr with vm.flagless) cause this backport not cleanly. And I think we do not have good reason to backport JDK-8318098 first.

Change has been verified locally by run the test manually on linux-x64. Test-fix only, no risk.
