 This [`java.util.Set`](https://docs.oracle.com/javase/8/docs/api/java/util/Set.html) relies on identity (`==`) to compare the objects it
 contains. It does not matter what the objects' [`equals`](https://docs.oracle.com/javase/8/docs/api/java/lang/Object.html#equals-java.lang.Object-) methods say.
