Run the attached test program, CalendarTest.java. The program tries to load the SHORT_STANDALONE display name of weekday.

When adapter list is JRE,CLDR, the short display name in CLDR is loaded. I check the resource files in JDK. Format_zh_CN.class and Format_zh.class are in JRE resources. In CLDR resource, there is only Format_zh.class. There is also no standalone.DayAbbreviations in all these files. The expected output should be from JRE adapter, when adapter list is JRE,CLDR.

This problem only happens in zh_CN. In other locales I checked (en_US, de_DE and ja_JP), the short display name is loaded from resource file in JRE when adapter list is JRE,CLDR. Attached is the screenshot of the output.
