Subject [jira] Created: (HARMONY-2793) [classlib][awt] java.awt.image.IndexColorModel.getNormalizedComponents throws IllegalArgumentException on Harmony instead of ArrayIndexOutOfBoundsException
Date Tue, 19 Dec 2006 13:33:21 GMT
[classlib][awt] java.awt.image.IndexColorModel.getNormalizedComponents throws IllegalArgumentException
on Harmony instead of ArrayIndexOutOfBoundsException
-----------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2793
                 URL: http://issues.apache.org/jira/browse/HARMONY-2793
             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)
"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 shows that Harmony throws IllegalArgumentException instead of
ArrayIndexOutOfBoundsException.

Test for reproducing:
------------- test.java -------------------
import junit.framework.TestCase;
import java.awt.*;
import java.awt.image.*;
public class test extends TestCase {      
    public void test1 () { 
        try {            
            IndexColorModel obj=new IndexColorModel(1,1,new byte[]{1,1,1},0,false);
            obj.getNormalizedComponents(new int[] {1,-23,5,67,89,0}, 1, new float[] {1,-23,5,67,89,0},
200);          
            fail("ArrayIndexOutOfBoundsException should be thrown");
        } catch (ArrayIndexOutOfBoundsException e) {
            //expected  
        }
    }       
}
-------------------------------------------
Output on RI:
==================

Time: 0

OK (1 test)

Output on Harmony:
==================
1) test1(test)java.lang.IllegalArgumentException: The length of normComponents minus normOffset
is less than numComponents
