Ah, static methods of interfaces behave differently to class methods. 
The language corner case I'm missing is in 8.4.8 (of Java SE 8 JLS) for 
classes

   "A class does not inherit static methods from its superinterfaces."

and 9.2 for interfaces (if I've parsed this correctly)

   "The interface inherits, from the interfaces it extends, all members 
of those interfaces, except for fields, classes, and interfaces that it 
hides; abstract or default methods that it overrides (9.4.1); and static 
methods."
