With what cards would you call or fold with this position? I didn't have high amount of hands on them (around 15-20) and they seemed tight.
I assumed first all-in had AQo or higher and the first person had AA, AK, KK, QQ so there was no way I could call this. I would personally fold anything but AA, KK.
What is really nasty about this spot is that utg+1 puts in half his stack where he should have an easy iso/reshove. Beginners/fishes and nits tend to be superstrong in such spots. No way you can fold QQ though (generally a good advice in ssmtt preflop btw) and i think you should still go with JJ here. He might have a whole lot of Ax hands.
