Is this a SimpleDateFormat bug?

Question

Hello to all.
Consider a SimpleDateFormar with a pattern: "dd-MM-yyyy"
I think the string "01-01-2010mwwwwwwwwwwwwwww" does not satisfy the pattern, but the following code shows the contrary.
Anyone can explain why?
public static void main(String[] args) throws Exception {
    SimpleDateFormat df = new SimpleDateFormat("dd-MM-yyyy");
    Date date = df.parse("01-01-2010mwwwwwwwwwwwwwww");
    System.out.println(date);
}Thanks

There might be another way to do this (confirm that a string contains a valid date and only a valid date), but I don't know what it is.That would be the parse(String, ParsePosition) method (check the API docs). Give it a ParsePosition object which says "Start at the first position", then call the method. When it returns it will have updated the ParsePosition object; you can look at that to see if the current position is past the end of the String, or whatever.
Pretty clunky, really, but I guess when you work with the Date and Calendar class your mind becomes poisoned and you find yourself producing more weird designs like this one.
