Pathiterator is inconsistent between GeneralPath and Area objects

Name: jk109818 Date: 12/07/2001


java version "1.2.1"
Solaris VM (build Solaris_JDK_1.2.2_05,native threads,subwjit)

Querying the pathiterator returns two different set of coordinates for the same
geometry.

Run this example:

import java.io.*;
import java.util.*;
import java.awt.geom.GeneralPath;
import java.awt.geom.*;
import java.awt.*;

import java.lang.Math;

public class tempShape {


 public static void getPoints(PathIterator pi){
  double [] coords = new double[6];
  int curseg;
  Point2D.Double p;
  while (!pi.isDone()){
    curseg = pi.currentSegment(coords);
    switch(curseg){
      case PathIterator.SEG_MOVETO:{
         p = new Point2D.Double(coords[0],coords[1]);
System.out.println("MOVE TO:"+p.x+" "+p.y);
          break;
      }
      case PathIterator.SEG_LINETO:{
         p = new Point2D.Double(coords[0],coords[1]);
System.out.println("LINE TO:"+p.x+" "+p.y);
          break;
      }
      case PathIterator.SEG_CLOSE:{
System.out.println("CLOSE");
           break;
      }
      default:{
        System.out.println("Undefined Seg type");
        break;
      }
    }
    pi.next();
  }
 }
 public static void main(String args[]){
    GeneralPath gp = new GeneralPath(GeneralPath.WIND_EVEN_ODD);
    gp.moveTo(40705662f, 104785693f);
    gp.lineTo(40705878f, 104785687f);
    gp.lineTo(40705845f, 104785332f);
    gp.lineTo(40705799f,104784340f);
    gp.lineTo(40706901f, 104784342f);
    gp.lineTo(40706896f, 104785325f);
    gp.lineTo(40706900f, 104785409f);
    gp.lineTo(40706878f, 104785483f);
    gp.lineTo(40706813f, 104785578f);
    gp.lineTo(40706776f, 104785621f);
    gp.lineTo(40706720f, 104785684f);
    gp.lineTo(40705846f, 104785691f);
    gp.lineTo(40705662f, 104785693f);
    gp.closePath();
    Area a = new Area(gp);
    System.out.println("****POINTS FROM GENERALPATH OBJECT****");
    getPoints(gp.getPathIterator(null));
    System.out.println("****POINTS FROM AREA OBJECT****");
    getPoints(a.getPathIterator(null));
 }
}



The results from gp.getPathIterator and a.getPathIterator should be the same.
But they are not.

Results returned:

The same problem was duplicated on java version 1.3.1-b24 on NT. The second path
 (5 points) returned from the Area object is inaccuarate and extraneous.
