--------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2698
                 URL: http://issues.apache.org/jira/browse/HARMONY-2698
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Alexander Simbirtsev


Harmony for getPreferredInnerHorizontal()/getPreferredInnerVertical() methods
returns null while RI throws NPE. 
Compatibility issue.

Use the following code to reproduce:

import java.awt.Dimension;

import javax.swing.plaf.basic.BasicProgressBarUI;

import junit.framework.TestCase;

public class Test extends TestCase {
    public void testcase1() {                                    
        try {                   
            testBasicProgressBarUI pb = new testBasicProgressBarUI();
            pb.getPreferredInnerHorizontal(); 
            fail("No NPE thrown"); 
        } catch (NullPointerException e) { 
            // expected;
        }
    }
    
    public void testcase2() {                                    
        try {                   
            testBasicProgressBarUI pb = new testBasicProgressBarUI();
            pb.getPreferredInnerVertical(); 
            fail("No NPE thrown"); 
        } catch (NullPointerException e) { 
            // expected;
        } 
    }                                                                        
}

class testBasicProgressBarUI extends BasicProgressBarUI {
     public Dimension getPreferredInnerVertical()  {
         return super.getPreferredInnerVertical();
     }
     
     public Dimension getPreferredInnerHorizontal()  {
         return super.getPreferredInnerHorizontal();
     }     
}
