> Make sure AquaTextPasswordFieldUI can't use selectWordAction.
> 
> The core problem here was we could call selectWordAction in the Aqua LAF on a JPasswordField. This problem was already solved in the BasicPasswordFieldUI, but the AquaTextPasswordFieldUI (and SynthPasswordFieldUI) do NOT extend the BasicPasswordFieldUI, so they weren't inheriting this solution.
> 
> So the problem is partially about multiple inheritance.
> 
> My first response at solving the problem is just to move the existing solution to the parent BasicTextUI class and use an instanceof to make sure it is only applied to JPasswordFields.
> 
> There may be many different philosophies/recommendations on how to resolve this; I'm open to suggestions.
