Description

The following Raster methods should throw RasterFormatException if w or h is less than or equal to zero according to the API spec:
createBandedRaster(int dataType,int w,int h,int scanlineStride,int[] bankIndices,int[] bandOffsets,Point location)
createPackedRaster(int dataType,int w,int h,int bands,int bitsPerBand,Point location)
createInterleavedRaster(DataBuffer dataBuffer, int w, int h, int scanlineStride, int pixelStride, int[] bandOffsets, Point location)
createInterleavedRaster(int,int,int,int,int,int[],Point)

They follow the specification on Harmony, but RI implementation throw unspecified IllegalArgumentException in this case.

The following testcase demonstrates this behavior (passes on RI but fails on Harmony):

package java.awt.image;

import junit.framework.TestCase;

import java.awt.*;

public class RasterTest extends TestCase {
public void testcase0() {
try {
Raster.createBandedRaster(1, -10, 10, 10, new int[]

{0}, new int[] {0}

, new Point());
fail("Exception expected");
} catch (RasterFormatException expectedException)

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

catch (IllegalArgumentException expectedException)

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

}
}

I think Harmony should folow specification in this case and suggest to treat it as a non-bug difference.
