The following JDKs will display the wrong DST for Australia/Sydney timezone:

java 1.3.0     incorrect
java 1.2.2_09  incorrect
java 1.2.2_08  incorrect
java 1.2.2_07a incorrect
java 1.2.2_06  incorrect

My test program is below:

import java.util.*;

public class LocalTime{
    public static void main(String args[]){
        Calendar c = Calendar.getInstance();
        String des, delim = "[],";
        StringTokenizer destok;

        System.out.println(new Date().toString());

        des = c.toString();
        destok = new StringTokenizer(des, delim);
        System.out.println("System default calendar settings:");
        while (destok.hasMoreTokens())
            System.out.println("  " + destok.nextToken());
    }
}

Test Cases:

After running the program, the differences in the output from JDK 1.3.1, 1.2.2.07a, and 1.2.2.06 are:

startMonth=9     jdk 1.3.1
startMonth=7     jdk 1.2.2.07a and 1.2.2.06

startTimeMode=1  jdk 1.3.1
no such attr     jdk 1.2.2.07a and 1.2.2.06

endTime=7200000  jdk 1.3.1
endTime=10800000 jdk 1.2.2.07a and 1.2.2.06

endTimeMode=1    jdk 1.3.1
no such attr     jdk 1.2.2.07a and 1.2.2.06

HOUR=6,HOUR_OF_DAY=18  jdk 1.3.1
HOUR=7,HOUR_OF_DAY=19  jdk 1.2.2.07a and 1.2.2.06

DST_OFFSET=0           jdk 1.3.1
