java.util.GregorianCalendar incorrectly works in server mode with
some TimeZones and Locales. The output of getTime() is different
for the same date in different modes.

This is the test demonstrating the bug:
------------------------------------------------------------------
import java.util.*;

public class TZ {

    public static void main (String args[]){

        long day = 1000*60*60*24;
        Date d = new Date(-5000*day);
        System.out.println("Date: " + d);

        String[] ids = TimeZone.getAvailableIDs();
        Locale[] locales = Locale.getAvailableLocales();
        for (int i = 0; i < ids.length; i++) {
            TimeZone tz = TimeZone.getTimeZone(ids[i]);
            TimeZone.setDefault(tz);

            for (int j = 0; j < locales.length; j++) {
                Locale loc = locales[j];
                Locale.setDefault(loc);

                GregorianCalendar calendar = new GregorianCalendar(tz, loc);
                calendar.setTime(d);
                if ( calendar.get(Calendar.DAY_OF_MONTH) < 23) {
                    System.out.println("Test failed with ");
                    System.out.println(" TimeZone: " + tz);
                    System.out.println(" Locale: " + loc);
                    System.out.println(" date: " + calendar.getTime());
                    return;
                }
            }
        }
        System.out.println("Test passed");
    }
}
