Call an all-in raise with JJ on Qxx flop?

[KY Seabee]

I've taken a long break (about a year) from poker (due to career reasons, not tilt/losing/etc). I've found I'm getting a little rusty. What would you do in my position on the flop? I was uneasy making the call thinking only a Jack or running hearts would save me, but thought I had the odds. MTT with not much info on button.
