[JDK-8352638](https://bugs.openjdk.org/browse/JDK-8352638) added final to public classes in `java.desktop/windows` including the Windows L&F package as a code consistency cleanup. This breaks applications that extend UI classes and they get `IncompatibleClassChangeError` at runtime.
Although this package is not part of the public API, we decided to remove the final modifier from all public and protected classes, as well as their inner classes in `com.sun.java.swing.plaf.windows`. Package-private classes, private inner classes, and the `@Override` annotations introduced by JDK-8352638 remain unchanged. Notes: - Most of the changed files are UI delegates or related classes, the next public utility classes `WindowsBorders`, `WindowsIconFactory` and `WindowsGraphicsUtils` are not reverted. ------------- Commit messages: - Update bug4991587.java - Update WindowsBorders.java - year - Skip "utility" classes - Merge branch 'master' into JDK-8359433 - Update WindowsMenuUI.java - 8359433: The final modifier on Windows L&F internal UI classes prevents extending them in apps Changes: https://git.openjdk.org/jdk/pull/30170/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=30170&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8359433 Stats: 91 lines in 41 files changed: 0 ins; 0 del; 91 mod Patch: https://git.openjdk.org/jdk/pull/30170.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/30170/head:pull/30170 PR: https://git.openjdk.org/jdk/pull/30170
