      Description

      See the result below from the test prgram:

      import java.text.*;
      import java.util.*;

      class dttest {
              static final int[] format = {
                      DateFormat.FULL,
                      DateFormat.LONG,
                      DateFormat.MEDIUM,

              public static void main(String[] arg) {
                      Date date = new Date();
                      for (int i = 0; i<format.length; i++) {
                              DateFormat fmt = DateFormat.getDateTimeInstance(format[i],
                              format[i]);
                              DateFormat fmt_en = DateFormat.getDateTimeInstance(format[i],
                              format[i], Locale.ENGLISH);
                              System.out.println(fmt.format(date));
                              System.out.println(fmt_en.format(date) + "\n");
                      }
              }
      }

      Problems:
        Time zone is always GMT+09:00 under ja locale.
        because kZoneStrings in DateFormatZoneData_ja containes incorrect timezone
        string.
        This is 116 regression.

        Formatted date and time is inconsistent between Japanese and English locale.
        The full format on 1.1.5 has the day of the week, but 1.1.6 doesn't.
        English has AM/PM but not for Japanese on both 1.1.5 and 1.1.6.
        This is probably RFE.

        Era definition is missing for Japanese locale.
        This is regression.
        There is no equivarent entry in LocaleElement
                  { "Eras",
                      new String[] { // era strings
                          "BC",
                          "AD"
                      }
        for Japanese locale. It should be translated to Kigenzen and Kigengo.
