when I was getting on single player on to a new world I expected to be able to build and have fun running around. but what really happened was I got on making a new world and I walked around normally and started flying ok then I went to go down and land and I was starting to jump when the hole game crash and I have to start over getting back on Minecraft it said to report a bug and a bunch of random stuff then and it said something about java run time when I don't even have java like what the heck
this is how I triggered it

1. make a new single player world on amplified or I can be customized
2. walk of fly around for about a minute
3. start to jump and it crashes that is how
