Steps:
 Run attatched test with JDK9 b123 build
 $JAVA_HOME/bin/java -Djava.locale.providers=JRE,CLDR localename

Expected result:
On de_DE locale, ss should get Swasil\u00e4ndisch
On ja_JP locale, mg should get \u30de\u30e9\u30ac\u30b7\u30fc\u8a9e
On zh_CN locale, tl should get \u5854\u52a0\u8def\u65cf\u6587
