Java 1.7中的SimpleDateFormat中的行为更改？

Question

Consider following snippet

public class Test1 {
    public static void main(String[] args) throws ParseException, java.text.ParseException {
        SimpleDateFormat f = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
        f.setLenient(false);
        String dateStr = "2008-01-23 00:00:00.0";
        Date date=f.parse(dateStr);
        System.out.println(date);

    }
}

this works fine in java 1.6 and gives output Wed Jan 23 00:00:00 IST 2008

In case of java 1.7 it gives Exception

Exception in thread "main" java.text.ParseException: Unparseable date: "2008-01-23 00:00:00.0"
    at java.text.DateFormat.parse(DateFormat.java:357)

I think JAVA 1.7 behavior is correct because 00:00:00.0 doesn't come under hh:mm:ss format (1-12 hr format)

Is my assumption is correct that 1.6 has bug and is corrected in 1.7?

Yes, this behaviour has changed with Java 7. The bugfix documentation can be found on Oracle website . The bug-id is JDK-4396385.
