Subject [jira] Created: (HARMONY-6198) [java6][classlib][sql] Timestamp.compareTo returns incorrect result

[java6][classlib][sql] Timestamp.compareTo returns incorrect result

                 Key: HARMONY-6198
                 URL: https://issues.apache.org/jira/browse/HARMONY-6198
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
    Affects Versions: 5.0M9
            Reporter: Jim Yu
             Fix For: 5.0M10

I found Timestamp.compareTo(Date) would return 1 even when both the timestamp and date object
are constructed with the same millisecond values. There is testcase below. I've made a fix
to solve the problem.

import java.sql.Timestamp;
import java.util.Date;

public class TimeStampComp {

     * @param args
    public static void main(String[] args) {

        long time = System.currentTimeMillis();
        Date date = new Date(time);
        Timestamp timestamp = new Timestamp(date.getTime());

        System.out.println("compareTo returns " + timestamp.compareTo(date));



Result of RI:
compareTo returns 0

Result of Harmony:
compareTo returns 1
