This PR is for [JDK-8223737](https://bugs.openjdk.org/browse/JDK-8223737), which is a real JDK code change
It is the dependency of [JDK-8314517](https://bugs.openjdk.org/browse/JDK-8314517), which is a test case backport

So add this real JDK change to OpenJDK 11 for a test case is not a good idea, if the [JDK-8223737](https://bugs.openjdk.org/browse/JDK-8223737) itself is not required.

We will close this PR.
