"Unparseable date"

[Ben Bucksch]

import java.util.*;
DateFormat dp = new SimpleDateFormat("yyyyMMddHHmmss z");
Date start = dp.parse("20081001175000 CET");

returns "Unparseable date" on OpenJDK 6 on Ubuntu 8.04.1 server, but works with Sub Java 6 on Gentoo.

I suspect it doesn't understand the timezone "CET" and expects a numerical ("+0100" or "+0200", depending on summer / winter time)?

Works with sun-java6-jre: It works when I remove openjdk-6-jre-headless and use the Sun Java 6 in Ubuntu. So, this is clearly an openJDK problem.

I don't see any such problem on hardy with openjdk. What is the version of openjdk you are using? Mine is 6b11-2ubuntu2 which is available in hardy-updates.

Here is how I used your sample code.
import java.util.*;
import java.text.*;

public class DateTest{
        public static void main (String args[]){
                DateFormat dp = new SimpleDateFormat("yyyyMMddHHmmss z");
                try {
                        Date start = dp.parse("20081001175000 CET");
                } catch (Exception e){
                        System.out.println(e);
                        e.printStackTrace();
                }
        }
}

Works OK for me using java-1.6.0-openjdk-1.6.0.0-0.18.b09.fc9.x86_64 on Fedora. If I println start in your test case, I get the following text, with no exceptions:

Wed Oct 01 12:50:00 EDT 2008

Works for me with java-1.6.0-openjdk-1.6.0.0-0.23.b12.fc10.i386 (Icedtea 1.3) on Fedora.

I also confirm no issues.
