JDK-8181157 introduced timezone aliases from CLDR. timezone display names for a timezone should match for a timezone and its corresponding alias.
e.g "Asia/Aden" is an alias of "Asia/Riyadh".
both these timezones should have same display names. however, this is not currently true for some timezones.
JDK-8206965java/util/TimeZone/Bug8149452.java failed on de_DE and ja_JP locale.
