This is not acceptable:

```groovy
public interface NewThing {
    Property<String> getSomeProperty()
}

abstract class DefaultNewThing implements NewThing {
    private final Property<String> someProperty
    DefaultNewThing(ObjectFactory objects) {
       someProperty = objects.property(String.class)
    }
    public Property<String> getSomeProperty() {
        return someProperty
    }
