Block models do not render using Java 10 (ConcurrentModificationException)
On 18w43b Minecraft can't load block models for almost all blocks, when using Java 10 or up.
This is an example of the console messages:
18:19:49 dij Unable to bake model: 'minecraft:note_block#instrument=bell,note=7,powered=true': java.util.ConcurrentModificationException
Created Issue:
Unable to bake model
I was using a resource pack when I started 18w43b, then I opened a world I made in 18w43a and Minecraft could not load almost all block models. Then I removed the resource pack and the issue still remains.

How does it act when using Java 8?? I might be wrong, but I remember that Minecraft isn't meant to run on Java 10...
It worked perfectly fine in Java 10 in 18w43a. But the b snapshot broke it. When I switched to the built-in version of Java (which, I suppose, is Java 8), everything was fixed.
I'm having the same problem, but it's with any java version greater than 8. I've tried with 9, 10, and 11. Switching back to 8 does fix the issue, but this wasn't a problem with earlier versions of the game.
Most blocks look fine in the inventory and player hand and only have a missing texture when placed. Some items have missing textures in the inventory.
