Please review this PR which corrects the behavior of `Locale.Builder.setLanguageTag(String)` on the null and empty String case.
> Null and the empty string cause the builder to be reset Currently, NPE is thrown for a null tag, and ILE is thrown for an empty String. They are both corrected to not throw, and instead reset the state of the `Locale.Builder`. ------------- Commit messages: - The fix and reg test Changes: https://git.openjdk.org/jdk/pull/27734/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=27734&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8369452 Stats: 25 lines in 2 files changed: 20 ins; 0 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/27734.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/27734/head:pull/27734 PR: https://git.openjdk.org/jdk/pull/27734
