The GHA test runner report several failures.

1. Some failures are CA issues, which is fixing by [PR256](https://github.com/openjdk/jdk8u-dev/pull/526). It's unrelated to this PR.

2. Linux x86  `gc/concurrentMarkSweep/SystemGCOnForegroundCollector.java` report [crash](https://github.com/sendaoYan/jdk8u-dev-ysd/actions/runs/9836796651/job/27154077313) `CompactibleFreeListSpace::block_size(HeapWord const*)`, which has been recorded by [JDK-8303159](https://bugs.openjdk.org/browse/JDK-8303159), it's unrelated to this PR.
3. MacOS build fail, the GHA doesn't show any fail logs, maybe it's enviromental issue.
