FULL PRODUCT VERSION :
java version "1.7.0_65"
Java(TM) SE Runtime Environment (build 1.7.0_65-b17)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)


ADDITIONAL OS VERSION INFORMATION :
Linux larrylopez-wsl1 3.13.0-39-generic #66~precise1-Ubuntu SMP Wed Oct 29 09:56:49 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux




EXTRA RELEVANT SYSTEM CONFIGURATION :
The latest tzupdater.jar was applied: tzupdater-1.4.9-2014i

A DESCRIPTION OF THE PROBLEM :
Since the latest tzupdater-1.4.9-2014i was applied, we have had 26 cases of customers encountering exceptions in Calendar.getTime(), all using the timezone Asia/Ho_Chi_Minh

We have had to rollback that timezone file(jre/lib/zi/Asia/Ho_Chi_Minh) to temporarily fix the issue.

I tested all timezones and the following cause exceptions with the above code(all these are in the Asia/Ho_Chi_Minh file):
Asia/Ho_Chi_Minh
Asia/Saigon
VST



ADDITIONAL REGRESSION INFORMATION:
This was working using the previous data before the tzupdater-1.4.9-2014i was applied.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Apply latest tzupdater.jar ( tzupdater-1.4.9-2014i )

2. Compile and run this program to test all timezones:
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Locale;
import java.util.TimeZone;

public class Main {

    public static void main(String[] args) {
        for(String tz: TimeZone.getAvailableIDs()) {
            try {
                test(tz);
            }
            catch(Exception e) {
                System.out.println("failed: " + tz + " Exception: " + e);
            }
        }
    }
    public static void test(String tz) {
        TimeZone brokenTimeZone = TimeZone.getTimeZone(tz);
        DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, new Locale("en"));
        df.setLenient(false);
        df.setTimeZone(brokenTimeZone);
        Calendar calendar = df.getCalendar();
        calendar.set(1959, Calendar.DECEMBER, 31, 23, 0);
        ((SimpleDateFormat)df).set2DigitYearStart(calendar.getTime());
    }
}




EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
No exceptions should be reported.
ACTUAL -
The following exceptions occur:
failed: Asia/Ho_Chi_Minh Exception: java.lang.IllegalArgumentException: YEAR: 1959 -> 1960
failed: Asia/Saigon Exception: java.lang.IllegalArgumentException: YEAR: 1959 -> 1960
failed: VST Exception: java.lang.IllegalArgumentException: YEAR: 1959 -> 1960

ERROR MESSAGES/STACK TRACES THAT OCCUR :
failed: Asia/Ho_Chi_Minh Exception: java.lang.IllegalArgumentException: YEAR: 1959 -> 1960
failed: Asia/Saigon Exception: java.lang.IllegalArgumentException: YEAR: 1959 -> 1960
failed: VST Exception: java.lang.IllegalArgumentException: YEAR: 1959 -> 1960

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Change timezone to another like Asia/Bangkok or rollback jre/lib/zi/Asia/Ho_Chi_Minh file to previous version before tzupdater-1.4.9-2014i was applied.
