java.text.SimpleDateFormat.parse() incorrectly sets ParsePosition index

Name: dfC67450 Date: 01/15/98



The java.text.SimlpeDateFormat.parse(String, ParsePosition) incorrectly sets
ParsePosition index when String parameter contains incorrectly formatted date.
Javadoc says about java.text.DateFormat.parse(String text, ParsePosition pos) method:

     * @param pos On input, the position at which to start parsing; on
     * output, the position at which parsing terminated, or the
     * start position if the parse failed.

Here is the test demonstrating the bug:

-----------------Test.java------------------------
import java.text.*;
public class Test {
    public static void main (String args[]){
        SimpleDateFormat sdf = new SimpleDateFormat();
        String pattern = "'time' hh:mm";
        sdf.applyPattern(pattern);
        System.out.println("pattern: \"" + pattern + "\"");

      // works correctly
        ParsePosition pp = new ParsePosition(0);
        String text = "time 10:30";
        sdf.parse(text, pp);
        System.out.println(" text: \"" + text + "\"");
        System.out.println(" index: " + pp.getIndex());

      // works correctly
        pp = new ParsePosition(0);
        text = "time 10:x";
        sdf.parse(text, pp);
        System.out.println(" text: \"" + text + "\"");
        System.out.println(" index: " + pp.getIndex());

      // works wrong
        pp = new ParsePosition(0);
        text = "time 10x";
        sdf.parse(text, pp);
        System.out.println(" text: \"" + text + "\"");
        System.out.println(" index: " + pp.getIndex());

   }

}

---------Output from the test---------------------
pattern: "'time' hh:mm"
  text: "time 10:30"
  index: 10
  text: "time 10:x"
  index: 8
  text: "time 10x"
  index: 0
