Hi all
This issue looks like RI bug so I filed it as "Non-bug differences from
RI".
Spec doesn't say about any exceptions. Even if Polygon created with
empty point buffer (not null but zero length), method addPoint()
should reallocate buffer to append new point but RI throws
ArrayIndexOutOfBoundsException exception.
================= Test.java ===================
import java.awt.*;
public class Test {
static public void main(String[] args) {
Polygon p = new Polygon(new int[2], new int[2], 0);
p.addPoint(1, 1);
}
}
============= RI ====================
java.lang.ArrayIndexOutOfBoundsException
at java.awt.Polygon.addPoint(Polygon.java:262)
at Test.main(Test.java:8)
=========== Harmony ================
nothing
Comments?
I would agree with you and vote for RI bug. New Point should be appended
without exceptions if the initial total number of points is 0, espessially
taking into account the code
Polygon p = new Polygon();
p.addPoint(1, 1);
behaves on RI as expected.
Thanks,
Ilya.

Project: Harmony
Issue Type: Bug
Components: Non-bug differences from RI
Reporter: Denis Kishenko
Spec doesn't say about any exceptions. Even if Polygon created with empty
point buffer (not null but zero length), method addPoint() should reallocate
buffer to append new point but RI throws ArrayIndexOutOfBoundsException
exception. Seems like RI bug.
================= Test.java ===================
import java.awt.*;
public class Test {
static public void main(String[] args) {
// Polygon p = new Polygon(); it works
Polygon p = new Polygon(new int[2], new int[2], 0);
p.addPoint(1, 1);
}
}
