Subject [jira] Created: (HARMONY-2716) [classlib][swing] javax.swing.plaf.basic.BasicSpinnerUI.installNext/PreviousButtonListeners(Component c) throw unspecified ClassCastException

[classlib][swing] javax.swing.plaf.basic.BasicSpinnerUI.installNext/PreviousButtonListeners(Component
c) throw unspecified ClassCastException
---------------------------------------------------------------------------------------------------------------------------------------------

                 Key: HARMONY-2716
                 URL: http://issues.apache.org/jira/browse/HARMONY-2716
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
            Reporter: Alexander Simbirtsev


Harmony throws unspecified ClassCastException for BasicSpinnerUI.installNextButtonListeners(Component
c) and for BasicSpinnerUI.installPreviousButtonListeners(Component c) when passed in parameter
is not JButton
while RI works silently for this case.

Use the following code to reproduce:

import java.awt.Component;

import javax.swing.JLabel;
import javax.swing.plaf.basic.BasicSpinnerUI;

import junit.framework.TestCase;

public class Test extends TestCase {
    private static JLabel c = new JLabel();

    public void testcase1() { 
        BSUI localBasicSpinnerUI = new BSUI();
        try {
            localBasicSpinnerUI.installNextButtonListeners(c);
        } catch (ClassCastException unexpectedException) { 
            fail("ClassCastException thrown");
        }
    }

    public void testcase2() { 
        BSUI localBasicSpinnerUI = new BSUI();
        try {
            localBasicSpinnerUI.installPreviousButtonListeners(c);
        } catch (ClassCastException unexpectedException) { 
            fail("ClassCastException thrown");
        }
    }
}

class BSUI extends BasicSpinnerUI {
    public void installNextButtonListeners(Component c){
        super.installNextButtonListeners(c);
    }

    public void installPreviousButtonListeners(Component c){
        super.installPreviousButtonListeners(c);
    }
}
