This fix is to require to include `Locale.ROOT` in the returned arrays/set from `getAvailableLocales()` methods in various locale-sensitive classes. The implementation has been including `Locale.ROOT` since its inception, it is simply a doc clarification (+ a test case verifying it). Corresponding CSR has also been drafted: https://bugs.openjdk.java.net/browse/JDK-8276249
