[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-3851) Seam reflection has lower access than Java reflection
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
(...)
Caused by: java.lang.IllegalAccessException: Class org.jboss.seam.util.Reflections can not
access a member of class HiSayerBean with modifiers "protected"

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.
