Personally I don't see any reason why you would want to cast it.
Please use [highlight=Java]//code goes here...[/highlight] tags when posting your code
Re: Casting "null" when and why ?
ks = (s == null) ? (KeyStroke) null : KeyStroke.getKeyStroke(s);
If I saw anyone write code like that they would be on the receiving end of a headslap.
