Description

This seem to be a bug in RI .

The following code

import java.util.*;

public class Test {
public static void main (String[] args) {
for(int i = -116670; i > -116681; --i )

{ System.out.println("i=" + i + "\t, date=" + new Date(2, 3, i)); }

}
}

Prints in RI:

i=-116670 , date=Sun Oct 24 00:00:00 MSK 1582
i=-116671 , date=Sat Oct 23 00:00:00 MSK 1582
i=-116672 , date=Fri Oct 22 00:00:00 MSK 1582
i=-116673 , date=Thu Oct 21 00:00:00 MSK 1582
i=-116674 , date=Wed Oct 20 00:00:00 MSK 1582
i=-116675 , date=Tue Oct 19 00:00:00 MSK 1582
i=-116676 , date=Mon Oct 18 00:00:00 MSK 1582
i=-116677 , date=Sun Oct 17 00:00:00 MSK 1582
i=-116678 , date=Sat Oct 16 00:00:00 MSK 1582
i=-116679 , date=Thu Oct 28 00:00:00 MSK 1582
i=-116680 , date=Wed Oct 27 00:00:00 MSK 1582

prints in Harmony:

i=-116670 , date=Sun Oct 24 00:00:00 MSD 1582
i=-116671 , date=Sat Oct 23 00:00:00 MSD 1582

i=-116679 , date=Fri Oct 05 00:00:00 MSD 1582
i=-116680 , date=Thu Oct 04 00:00:00 MSD 1582

Harmony version is a correct calendar switch

and same functionality rewritten in another way works correctly in both implementations:

import java.util.*;

public class Test {
public static void main (String[] args) {
Calendar cal = new GregorianCalendar(1582, Calendar.OCTOBER, 29);
for(int i = 0; i < 20 ; ++i )

{ cal.add(Calendar.HOUR, -24); System.out.println(cal.getTime()); }

}
}
