NB 5.0 dev build 20050926
JDK 1.5.0_05

An error 'X does not override abstract method ..' not announced within anonymous
class. 

Steps to reproduce:
-------------------
1) create new interface:
public interface Itemable {
    void setOwner(Object owner);
    
}

2) create new class:
public class Owner {
    
    LinkedList ll = new LinkedList();
    
    public void add(Itemable it) {
        it.setOwner(this);
        ll.add(it);
    }
    
    public void meth() {
        this.add(new Itemable() {
            
        });
    }
    
}

-> this code can not be compiled because the anonymous class derived from
Itemable does not implement method setOwner(Object), but it is not announced in
the editor.
