Even if he can have AJ, there are still more combos of JJ+. He needs to be doing this with either AK or Jx sometimes as well for you to make that call down.
And Even if AJ can be in his range, it's still weighted towards KK+

At 4NL you never make too much of a mistake by folding, because a generic 4NL villain is extremely passive and you will not get exploited to the point of being unable to beat the stakes, even if you fold too much.

I agree with Miffed. I would call the flop and fold to another barrel.
