Subject [jira] Created: (HARMONY-367) BeanContextSupport.getResource(...) throws IllegalArgumentException instead of NullPointerException
Date Tue, 18 Apr 2006 07:08:18 GMT
BeanContextSupport.getResource(...) throws IllegalArgumentException instead of NullPointerException
---------------------------------------------------------------------------------------------------

         Key: HARMONY-367
         URL: http://issues.apache.org/jira/browse/HARMONY-367
     Project: Harmony
        Type: Bug

  Components: Classlib  
    Reporter: Dmitry M. Kononov
    Priority: Minor


Problem details:
java.beans.beancontext.BeanContextSupport.getResource(String name, BeanContextChild bcc):
Harmony throws IllegalArgumentException when name=null,bcc=null, while RI throws NullPointerException.
Specification does not mention neither NullPointerException nor IllegalArgumentException.

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

public class BeanContextSupportTest extends TestCase {
    public void test_getResourceLjava_lang_StringLjava_beans_beancontext_BeanContextChild()
{
        BeanContextSupport obj = new BeanContextSupport();
        boolean b = true;
        try {
            obj.getResource(null, null);
            b = false;
        } catch (NullPointerException t) {
            t.printStackTrace();
        }
        assertTrue(b);
    }
}

RI output:
