This was just marked as resolved in 1.14.3pre1... but I just tested and the issue is still present.
It's only fixed by upgrading to the newer Lwjgl manually.
Can others please test and confirm?
Following Dinolek's instructions above to load LWJGL 3.2.2 fixes the issue for me.
Yep, I'm an idiot. Please delete my shame. 😛
Ok. I just realized I got caught in between versions. I thought I was running the 'b' snapshot, but I was running 'a'. I bet that this bug is already fixed. Testing now. Sorry!
Another NullPointer crash
It's pretty consistently crashing. Always with the same error, on the same type of entity (Chicken).
I'm seeing this exact same issue with my snapshot SMP server with version 15w37a.
Ah ok! Thank you for the clarification.
