Most players don't bluffraise the river and they'll call too light so betting has a lot of value to it. He's definitely calling with any J, a smaller flush, and some Ax hands. He might raise with a J or a smaller flush as well as boats and the K high flush. Given the pot odds presented to the hero I think he has to call because villains at these stakes turn up with a naked J or lower flush way too often. If he shoves I think you have a pretty easy fold because your pot odds are terrible and you won't be ahead often enough except against the craziest of opponents.
