     Since you already need an instance of a class implementing
Bla before you can call getInstance() on it, what's the point?

     Perhaps you meant the interface to be BlaFactory (with getInstance()
still returning Bla)?

	BlaFactory factory = BlaFactoryProvider.defaultFactory();
	factory.setBlurg(86);
	Bla instance = factory.getInstance(42, 42.0, null);
