That’s the problem: the BasicOptionPaneUI spec says nothing about that parameter (unlike the parent class), and the implementation ignores it, instead checking the inputComponent and then the initialFocusComponent.

So the question is: how should the parameter passed to that method be handled, and what priority should it have compared to inputComponent and initialFocusComponent?
