[classlib][awt][compatibility] java.awt.image.RescaleOp(float[] scaleFactors, float[] offsets,
RenderingHints hints) throws IllegalArgumentException if an array is empty
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2691
                 URL: http://issues.apache.org/jira/browse/HARMONY-2691
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Oleg Khaschansky
            Priority: Minor


Specification doesn't mention any exceptions for
RescaleOp(float[] scaleFactors,float[] offsets,RenderingHints hints)
constructor.

Harmony throws IllegalArgumentException if scaleFactors or offsets is empty while RI does
not.

Testcase:

import java.awt.image.*;
import junit.framework.TestCase;
import java.awt.*;

public class test extends TestCase  {

    public void testcase1() {                           
        float[] array0 = new float[] {};
        float[] array1 = new float[] { 0.75F};
        new RescaleOp(array1, array0, null);                            
    }
    public void testcase2() {                           
        float[] array0 = new float[] {};
        float[] array1 = new float[] { 0.75F};
        new RescaleOp(array0, array1, null);                            
    }                                                                        
}
Output on RI:

Time: 0,016

OK (2 tests)

Output on Harmony+drlvm/j9:

Time: 0
There were 2 errors:
1) testcase2(test)java.lang.IllegalArgumentException: The number of scale
factors should not be zero
        at java.awt.image.RescaleOp.<init>(RescaleOp.java:47)

2) testcase3(test)java.lang.IllegalArgumentException: The number of scale
factors should not be zero
