 Description   

I placed a 2x2 minecart track under 8 dispensers and put maybe 15 or so normal minecarts on it. I then had the dispensers simultaneously place 8 TNT carts onto those 4 tracks. The game instantly slows down to 1 fps and eventually freezes and stops responding. The crash report says one of the tnt minecarts has

seems like a lot to me, especially if it explodes and deals damage based on speed.
When I reload the map after the crash I spawn where the screenshot is taken from. (I took the screenshot before pressing the button)

Duplicate of MC-6833.

Can confirm. Seems that when many minecarts are placed on a small section of rails and then a TNT minecart is added, momentum increases to the point where Java runs out of memory despite the carts appearing stationary or slow-moving.
