> java.beans.beancontext.BeanContextServicesSupport.hasService(Class c):
> Harmony does not throw NullPointerException when parameter c=null, while RI throws it.
> Specification doesn't say anything about NullPointerException throwing.
> Junit test to reproduce the problem:
> import junit.framework.TestCase;
> import java.beans.beancontext.BeanContextServicesSupport;
> public class BeanContextServicesSupportTest extends TestCase {
>     public void test_hasServiceLjava_lang_Class() {
>         BeanContextServicesSupport obj = new BeanContextServicesSupport();
>         boolean b = true;
>         try {
>             obj.hasService(null);
>             b = false;
>         } catch (NullPointerException t) {
>             t.printStackTrace();
>         }
>         assertTrue(b);
>     }
> }
> RI output:
