Seems crazy but I'm not hating the jam by villain.
It's pretty clear, by how the hand played out, that villain is trying to balance out their nut hand jams and their nut bluffs jams. Seeing as their jam only needs to work 51% of the time to be profitable, they've balanced out that range extremely well. Just unfortunate to run into QhJh in this spot but there will be times where you don't have anything at all and will have to fold.
In the short term, it looks like a bad play to a lot of newer/weaker players, but all good players know that 50% of the time, this jam works 100% of the time.
