> Harmony throws unspecified ArrayIndexOutOfBoundsException for java.awt.image.LookupOp.filter(BufferedImage src,BufferedImage dst) and java.awt.image.LookupOp.filter(Raster src, WritableRaster dst) while RI throws IllegalArgumentException. It is the case when src and dst have different width or height.
> Spec says nothing about the exceptions when width or height of dst and src are not equals however RI has checks for these parameters. It is a Exception throwing compatibility issue.
> Test to reproduce:
> ----------------test.java-------------------
> import java.awt.image.LookupOp;
> import java.awt.image.ByteLookupTable;
> import java.awt.image.BufferedImage;
> public class test {
>     public static BufferedImage getImage(int w, int h) {
>         return new BufferedImage(w, h, BufferedImage.TYPE_4BYTE_ABGR);
>     }
>     public static void main(String[] args) {
>         byte[] array0 = new byte[96];
>         ByteLookupTable localByteLookupTable = new ByteLookupTable(1, array0);
>         LookupOp localLookupOp = new LookupOp(localByteLookupTable, null);
>         BufferedImage localBufferedImage = getImage(5069, 19);
>         BufferedImage localBufferedImage1 = getImage(6, 19);
>         try {
>             localLookupOp.filter(localBufferedImage, localBufferedImage1);
>         } catch (Exception e) {
>             System.out.println("filter(BI,BI) non-equal widths: "  + e + " was thrown");
>         } 
>         try {
>             localLookupOp.filter(localBufferedImage.getRaster(), localBufferedImage1.getRaster());
>         } catch (Exception e) {
>             System.out.println("filter(WR,R) non-equal widths: " + e + " was thrown");
>         }
>         localBufferedImage1 = getImage(5069, 5);
>         try {
>             localLookupOp.filter(localBufferedImage, localBufferedImage1);
>         } catch (Exception e) {
>             System.out.println("filter(BI,BI) non-equal heights: " + e + " was thrown");
>         } 
>         
>         try {
>             localLookupOp.filter(localBufferedImage.getRaster(), localBufferedImage1.getRaster());
>         } catch (Exception e) {

> ====== Output RI ======= 
> filter(BI,BI) non-equal widths: java.lang.IllegalArgumentException: Src width (5069) not equal to dst width (6) was thrown
> filter(WR,R) non-equal widths: java.lang.IllegalArgumentException: Width or height of Rasters do not match was thrown
> filter(BI,BI) non-equal heights: java.lang.IllegalArgumentException: Src height (19) not equal to dst height (5) was thrown
