NullPointerException with setPaintOrder()?

For some reason I get a NullPointerException when I try to use my world. The error comes from this line of code:
?

setPaintOrder(HUD.class, LightActor.class, Ground.class, UseableActor.class, Background.class);
I've double checked, and all those classes do in fact exist in my program. I got the error when I added HUD. I think this may be because it's an interface, and not an actor. Would that assumption be correct?

Just tried it. Guess you can't use interfaces here. Abstract classes should work though.

Well a I already know abstracts work, LightActor and UseableActor are abstract. I wished interfaces would work. I don't want an empty abstract class that any HUD items need to extend, especially since a couple of the HUD implemented classes extend other objects...
