Subject [jira] Created: (HARMONY-370) BeanContextSupport.vetoableChange(...) does not throw NullPointerException
Date Tue, 18 Apr 2006 07:22:17 GMT
BeanContextSupport.vetoableChange(...) does not throw NullPointerException
--------------------------------------------------------------------------

         Key: HARMONY-370
         URL: http://issues.apache.org/jira/browse/HARMONY-370
     Project: Harmony
        Type: Bug

  Components: Classlib  
    Reporter: Dmitry M. Kononov
    Priority: Minor
 Attachments: BeanContextSupport.java.diff, BeanContextSupportTest.java

Problem details:
java.beans.beancontext.BeanContextSupport.vetoableChange(PropertyChangeEvent pce):
Harmony does not throw NullPointerException when pce=null, while RI throws it.
Specification does not mention NullPointerException.

JUnit test to reproduce the problem:
import junit.framework.TestCase;
import java.beans.beancontext.BeanContextSupport;
import java.beans.PropertyVetoException;

public class BeanContextSupportTest extends TestCase {
    public void test_vetoableChangeLjava_beans_PropertyChangeEvent() {
        BeanContextSupport obj = new BeanContextSupport();
        boolean b = true;
        try {
            obj.vetoableChange(null);
            b = false;
        } 
        catch (PropertyVetoException p) {
            p.printStackTrace();
            b = false;
        }
        catch (NullPointerException t) {
            t.printStackTrace();
        }
        assertTrue(b);
    
        
    }
}
RI output: 
java.lang.NullPointerException
