[jdk25] RFR: 8359830: Incorrect os.version reported on macOS Tahoe 26 (Beta)

Thu Jun 26 13:49:06 UTC 2025

Can I please get a review of this backport to JDK 25? This backports https://bugs.openjdk.org/browse/JDK-8359830 which was integrated into mainline a few minutes back https://github.com/openjdk/jdk/pull/25865.

With this change it should now be possible to test JDK 25 on macOS 26 when it gets released. Java's standard `os.version` system property will correctly report the version as 26 on macOS 26 once this is integrated.
