What I expected:
Minecraft to open the world without crashing

What happened:
Minecraft crashed upon opening the world

On June 2, 2016 I was playing in my survival world in 16w21b on my desktop, and learned that a new snapshot, 1.10-pre-1 was out, so I rebooted Minecraft and opened my Minecraft world. It crash almost immediately and did not give me a crash report. I did find a report in the game directory(see attachment), however it was not a Minecraft report. I tried down grading to 16w21b, and 1.9.4, and opened the world, and other worlds not opened in 1.10-pre-1 yet had the same problem. I looked up the problem in the bug tracker, and found bug MC-102917, a duplicate of bug MC-32606, I followed the instrutions listed in MC-32606 yet it did not resolve the problem. I updated Java, but that didn't work ether. I tried to replicate the problem on my laptop, but didn't succeed.
