Seems this is RI bug.
Apparently, RI doesn't comply with spec this time. But I think
IllealArgumentException is also acceptable. Therefore, I suggest to follow
RI and mark this issue as "Non-bug differences from spec" as
exception-throwing guideline[1] suggests. Thanks!

RI implementation of BufferedImage.isTileWritable(int,int) throws
IllegalArgumentException while Harmony throws
ArrayIndexOutOfBoundsException to follow spec.
========== Spec =============
public boolean isTileWritable(int tileX, int tileY)
Throws:
ArrayIndexOutOfBoundsException - if both tileX and tileY are not equal to
0
============ Test ================
import java.awt.image.*;
public class Test {
public static void main(String[] argv) {
BufferedImage img = new BufferedImage(10, 16,
BufferedImage.TYPE_4BYTE_ABGR);
img.isTileWritable(1,1);
}
}
========== RI output =============
java.lang.IllegalArgumentException: Only 1 tile in image
at java.awt.image.BufferedImage.isTileWritable(BufferedImage.java:1526)
at Test.main(Test.java:6)
========= Harmony output ========
java.lang.ArrayIndexOutOfBoundsException: Both tileX and tileY are not
equal to 0
at java.awt.image.BufferedImage.isTileWritable(BufferedImage.java:603)
So I have filed issue as non-bug.
Any comments?
