Years ago I grew some in Georgia from purchased seed of "thornless" origin. Most of the seedlings came up thornless, but I did notice that, out of 15 or 20 trees planted out, maybe 2 or 3 developed thorns later.....say two or three years after planting when they were head-high.
Just for fun, these are some SERIOUS thorns! One time I broke off several long ones....a couple of inches, and drove them up to their shanks into a pine 2x4 like nails!
