> 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 . The same solution was copied and pasted into the SynthPasswordFieldUI . But the AquaTextPasswordFieldUI does NOT extend either class with the 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. This should benefit all the PasswordFieldUI's (that I know about).
> 
> There may be many different philosophies/recommendations on how to resolve this; I'm open to suggestions.
