I think you play the hand fine, but can certainly fold unless you think he's fastplaying a pre-flop sandbagged AA.

He could also have AK of spades I suppose.... but it's very hard to get your entire stack in with that kind of aggression... with KJ... maybe... But I think it's likely you're facing a KJ or a JJ... low limit players are superstitious, stupid creatures sometimes who "Hate JJ" and won't throw it down, but won't raise with it either.
