GHA report several fials.

1. windows-x86 release/fastdebug build fails, seems can not get vs-2010 from internet. Maybe environmental or infrastructure issue, it's unrelated to this backport issue.
2. Macox x64 com/sun/jdi tests fails "gethostbyname: unknown host", seems like environmental issue, it's unrelated to this backport issue.

/approval request Clean backport to fix the test bug which cause test fails intermittently. Change has been verified locally, test-fix only, no risk.
