The copyright header changes are a bit odd, because `java/lang/System.java` is bumped to 2022 but `java/lang/VersionProps.java.template` is bumped to 2024. However, I think this is because the former matches the original 19u patch (as does `PolicyFile.java` which doesn't need bumping here as it's already 2023), while the `VersionProps.java.template` is a new change unique to 17 as it sets us to MR1.

So ok with me.
