I don't want to declare this PR a backport of [JDK-8223347](https://bugs.openjdk.org/browse/JDK-8223347), because it's only a very, very small part of it.
The idea of using the ID of [JDK-8295174](https://bugs.openjdk.org/browse/JDK-8295174) is not supported by Skara. It requires the ID to match the one in JBS which must be open. Otherwise, I'd get the error message "Issue is not open.".
I can only do this if you want to push it manually (bypassing Skara).
But, I can make [JDK-8295174](https://bugs.openjdk.org/browse/JDK-8295174) a backport of JDK-8289043 after integration. I think this should be sufficient.
