Subject [jira] Created: (HARMONY-2794) [classlib][awt]java.awt.image.IndexColorModel.getNormalizedComponents throws ArrayIndexOutOfBoundsException on Harmony while it does not on RI
Date Tue, 19 Dec 2006 13:43:21 GMT
[classlib][awt]java.awt.image.IndexColorModel.getNormalizedComponents throws ArrayIndexOutOfBoundsException
on Harmony while it does not on RI
----------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2794
                 URL: http://issues.apache.org/jira/browse/HARMONY-2794
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Ilya Okomin
            Priority: Minor


According to the specification for getNormalizedComponents(int[] components, int offset, float[]
normComponents, int normOffset):
"If the normComponents array is null, a new array will be allocated" and "an ArrayIndexOutOfBoundsException
is thrown if the normComponents array is not null and is not large enough to hold all the
color and alpha components (starting at normOffset)".

Test listed below sets normComponents==null. 
In this case RI does not throw an exception according to the specification while Harmony throws.
---------------- test.java-------------------
import junit.framework.TestCase;
import java.awt.*;
import java.awt.image.*;
public class test extends TestCase {      
    public void test1 () {             
          IndexColorModel obj=new IndexColorModel(1,1,new byte[]{1,1,1},0,
false);
          obj.getNormalizedComponents(new int[] {1,-23,5,67,89,0}, 1, null,
1002);

    }

}
