Bug 69700

Description Friedrich Steimann 2004-07-09 03:52:20 EDT

"Use Supertype" does not replace var's type by interface with identical 
protocol if class inherits a method from a superclass.

public class A {
    public void m(){    
    }
}

public interface I {
    void m();
    void n();
}

public class B extends A implements I {
	public void n() {
	}
	public void doIt() {
		B b = new B();
		b.m();
		b.n();
	}
}

Refuses to replace B with I. Works if m() is overridden in B.

Is this a feature?
