interface IMoney {
	public abstract IMoney add(IMoney m);
	public abstract IMoney addMoney(Money money);
}

class Money implements IMoney {
	public IMoney add(IMoney m) { // extract into superclass
		return m.addMoney(this);
	}

	public IMoney addMoney(Money money) {
		return null;
	}
}

Extracting Money#add(IMoney) into superclass MyMoney gives:

public class MyMoney extends Object {
	public MyMoney() {
		super();
	}

	public IMoney add(IMoney m) { // extract into superclass
		return m.addMoney(this);
	}

}

Method MyMoney#add(IMoney) has a compile error, since MyMoney is not an IMoney.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
