Hi all,

This pull request contains a backport of commit fe29cad5 from the openjdk/jdk repository.

The commit being backported was authored by Brent Christian on 6 May 2025 and was reviewed by Kim Barrett and Jaikiran Pai.

This PR is intend to fix the test bug which cause test intermittent fails. Backport not clean because the path of sun.hotspot.WhiteBox different to main-line, the path should adopt to jdk11u-dev when backport from main-line to jdk11u-dev, Other parts is cleanly.

I have verified this backport plus with https://github.com/openjdk/jdk11u-dev/pull/3105.

Thanks!
