Decouple the jdk.internal.util OperatingSystem and Version classes to simplify class loading and avoid an indirect cyclic initialization.
Move the method to get the current OS version from OperatingSystem to the Version class and its initialization. Revert to using String.toUpperCase() instead of custom code to uppercase. Update the uses of OperatingSystem.version to be Version.current. ------------- Commit messages: - 8308960: Decouple internal Version and OperatingSystem classes Changes: https://git.openjdk.org/jdk/pull/14181/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=14181&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8308960 Stats: 58 lines in 4 files changed: 24 ins; 29 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/14181.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/14181/head:pull/14181 PR: https://git.openjdk.org/jdk/pull/14181
