040606. I have an empty class (just a constructor)
and I make it implement an interface in another
module (which I have imported). No synchronize
dialog popped up, and there was no such menu item
in Tools, so I chose Override Methods.

All methods are displayed - those from Object, and
the interface methods. But if I click Show
Abstract Methods Only, they all disappear. The
interface methods should of course remain.

BTW the actual text of the interface does not use
the explicit "abstract" modified; just looks like

public interface X {
    void y();
    int z();
    // etc.
}
