This was a Kerr brand jar. I think I figured out what it is; either people aren't using ice like you do, or they are using ice from an ice machine, which is less dense so it crushes easily. My ice is in trays in the freezer so it's big and dense and hit that glass like a rock!

That might very well be it. As well as if you happen to take a jar that is warm or even hot. The shock of the temp difference could be a culprit. Try with a different cube and see how it goes. Smaller cubes less force. Let me know how it goes.
