> The behavior of Harmony implementation of the constructor ComponentSampleModel.getPixels(int,int,inrt,int,int[],DataBuffer) differs from RI in case of integer overflow. The following testcase demostrates this difference:
> --------------------------------------------------------------------------------------------------
> import junit.framework.TestCase;
> import java.awt.image.ComponentSampleModel;
> import java.awt.image.DataBufferInt;
> public class Test0 extends TestCase {
> public void testcase0(){
> ComponentSampleModel csm = new ComponentSampleModel(0, 10, 10, 1, 10, new int[]{0});
> DataBufferInt dbi = new DataBufferInt(100);
> try {
> int[] returnValue = csm.getPixels(8, Integer.MAX_VALUE, 1, 1, (int[])null, dbi);
> fail("Exception expected");
> } catch(ArrayIndexOutOfBoundsException expectedException) {
> System.out.println(expectedException + " was thrown");
> }
> }
> }
> --------------------------------------------------------------------------------------------------
> Harmony:
> junit.framework.AssertionFailedError: Exception expected
> at Test0.testcase0(Test0.java:32)
> at java.lang.reflect.AccessibleObject.invokeV(AccessibleObject.java:25)
> RI:
> java.lang.ArrayIndexOutOfBoundsException: -2 was thrown
