Seam reflection has lower access than Java reflection
-----------------------------------------------------

                 Key: JBSEAM-3851
                 URL: https://jira.jboss.org/jira/browse/JBSEAM-3851
             Project: Seam
          Issue Type: Bug
    Affects Versions: 2.0.2.SP1
         Environment: Jboss Embedded, Java 5
            Reporter: Gabriel Goïc


This simple class is to be unit-tested, the SeamTest way:

@Name("hibean")
public class HiSayerBean {
    
    public HiSayerBean () {
    }

    protected void sayHi(){
        System.out.println("hello");
    }
}

All tests occur in the SeamTest framework:
new ComponentTest() {
    @Override
     protected void testComponents() throws Exception {
                //test code
     }
}.run();

Using Java Reflection - works:

HiSayerBean impl = new HiSayerBean();
Method m = impl.getClass().getDeclaredMethod("sayHi");
m.setAccessible(true);
m.invoke(impl);

Using Java Reflection with Seam - fails:

HiSayerBean impl = (HiSayerBean) getInstance("hibean");
Method m = impl.getClass().getDeclaredMethod("sayHi");
m.setAccessible(true);
m.invoke(impl);

Error log:

java.lang.reflect.InvocationTargetException
        (...)

So, using Seam gives me a lower capacity to access methods in a  reflected class than with raw Java. I'm not sure if it's a bug or a feature request though. But it would be nice to be granted to do this in unit-testing.

Please note that access to a private method in the same way than above works with Java but produces a java.lang.NoSuchMethodException with Seam.
