[classlib][awt] BufferedImage constructor throws different exceptions on RI and Harmony 
----------------------------------------------------------------------------------------

                 Key: HARMONY-1655
                 URL: http://issues.apache.org/jira/browse/HARMONY-1655
             Project: Harmony
          Issue Type: Bug
          Components: Non-bug differences from RI
            Reporter: Denis Kishenko


Constructor of BufferedImage throws different exceptions on RI and Harmony if width or height
is negative. Type of exception depends on BufferedImage type parameter. There are 13 different
types exist. Results are listed below.

1-4 IllegalArgumentException both
5-7 RI - NegativeArraySizeException, Harmony - RasterFormatException
8-9 IllegalArgumentException both
10-11 RI - NegativeArraySizeException, Harmony - IllegalArgumentException
12-13 RI - NegativeArraySizeException, Harmony - RasterFormatException

I think this is non-bug difference because of

5-7 and 12-13: As you see from stack trace both implementations call Raster.createInterleavedRaster(...)
Spec says
  Throws: 
       RasterFormatException - if w or h is less than or equal to zero, or computing either
location.x + w or location.y + h results in integer overflow 
So RI doesn't folow spec while Harmony does.

10-11: For RI the same situation as listed above while Harmony just has another implementation
and exception order. 

In all cases it's more logical to throw IllegalArgumentException or RasterFormatException
instead of NegativeArraySizeException.

=========== Test  ==========
import java.awt.image.*;

public class Test {
   public static void main(String[] argv) {
       for(int i = 1; i < 14; i++) {
           try {
               System.err.println(i);
               new BufferedImage(8, -7, i);
           } catch (Exception e) {
               e.printStackTrace();
           }
       }
   }
}
