> Fixing the NPE in CLDR time zone name provider. The NPE occurrs if the time zone data was downgraded by the TZUpdater tool in which some time zones are missing. For those missing zones, `ZoneInfo.getTimeZone()` returns null, while `TimeZone.getTimeZone()` falls back to `GMT`, which was the case prior to JDK-8342550. Changed the code in CLDR provider to assume the fixed zone in such a case.
