Description

RI throws unspecified NPE while Harmony throws specified ArrayIndexOutOfBoundsException. API specification says: "ArrayIndexOutOfBoundsException - if bankIndices or bandOffsets is null". This issue seems to be mostly RI problem. I think it is a non-bug difference from RI.

Testcase:

import junit.framework.TestCase;
import java.awt.Point;
import java.awt.image.Raster;
import java.awt.image.WritableRaster;
import java.awt.image.RasterFormatException;
public class test extends TestCase
{
public void testcase0()
{
int[] array0 = new int[] {};
int[] array1 =null;
Point localPoint = new Point(-17796, 8);
try

{ Raster.createBandedRaster(9,65412,5,-1,array0,array1,localPoint); assertEquals(true, false); }

catch (IllegalArgumentException expectedException)

{ fail(expectedException +" was thrown"); }

catch (ArrayIndexOutOfBoundsException expectedException)

{ System.out.println(expectedException +" was thrown"); assertEquals(true,true); }

}
}

If array1 is just empty (not null!) RI also throws ArrayIndexOutOfBoundsException while Harmony throws IllegalArgumentException , which is correct. So it's RI's behavior contradicts the spec.
