Problem description
===================
java.util.GregorianCalendar.isLeapYear(1000) returns false with GMT offsets >= 10.
Year 1000 is leap in both julian and gregorian calendars so this method should return true.


    
Minimized test:
===============
------- Test.java -------
import java.util.*;

public class Test {
    public static void main (String [] args) {
        String tz [] = {"GMT+8", "GMT+9", "GMT+10", "GMT+11", "GMT+12"};
        for (int i = 0; i < tz.length; i++) {
            GregorianCalendar calendar =
                new GregorianCalendar(TimeZone.getTimeZone(tz[i]));
            calendar.set(1001, 0, 1);
            calendar.setGregorianChange(calendar.getTime());
            System.out.println("calendar = GregorianCalendar(" +
                               "TimeZone.getTimeZone(\"" +
                               tz[i] + "\"))");
            System.out.println("calendar.isLeapYear(1000) = " +
                               calendar.isLeapYear(1000));
            System.out.println();
        }
