This clean-up PR removes unused Windows version macro from `ShellFolder2.cpp`.
`IS_WINVISTA` was not used at all. `IS_WINXP` guarded support for icons with alpha channel. It is now safe to assume Java runs on a Windows version later than Windows XP. Java launchers specify 6.0 as the minimum OS version which corresponds to Windows Vista. ------------- Commit messages: - 8289770: Drop IS_WINVISTA macro from ShellFolder2.cpp Changes: https://git.openjdk.org/jdk/pull/18736/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=18736&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8289770 Stats: 18 lines in 1 file changed: 0 ins; 13 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/18736.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18736/head:pull/18736 PR: https://git.openjdk.org/jdk/pull/18736
