For anyone else having these crashes with a ConcurrentModificationException either on resource reload or when starting the game. Limiting the number of CPUs visible to Java seemed to be a work around. Just add the following argument to in your launcher configuration:

-XX:ActiveProcessorCount=4

I assume this may impact performance. I guess what is happening here is that Minecraft spawns a number of worker threads depending on the amount of CPUs the machine has and be reducing this, it also reduces the risk for a concurrent access to a certain resource. However, this is all wild guess. Anyway, my friends and I can play with this mod in our modpack now. Feel free to close this issue. Maybe this helps someone.

Fairly sure minecraft runs on a single core, this shouldn't impact performance.
