I'm pretty confident that not calling was correct. Villain had been at our table for about 15 hands and had folded every time except for once when he squeezed with a shove. I would normally think of this as an unbreakable jack but 5-handed it's too good to fold. I hate flatting jacks for the obvious reason of playing the hand face-up. If he draws and I pat I'm in a gross spot when he leads. I suppose flatting and chopping around for a small pot here would have been the better part of valor. As it was, once he raised and we had chips behind I thought I could shove and hope he was drawing (again, hadn't seen a single showdown for him) or fold since I break to a straight draw.
Anyway, any thoughts appreciated. When this hand was over I was so conflicted.
