[1.8.9] The wonderful crash of "NoClassDefFoundError"...

[dev909]

Well if you clicked on this thread then most likely you know what the error is about. I do not. I have googled around and it almost seems like for every thread I found, they was a different unique-ish solution. Here's the crash report:

I don't understand what's happening...

[dev909]

scala/actors/threadpool/Arrays

- Why are you using this class (hint: you shouldn't be using it).

 

I thought it was weird too. But as far as I remember.....I didn't use it. I thought it was just some random underlaying forge class

[dev909]

Ah. I did. In a few classes actually. Weird, I don't remember actually importing it. Oh well, I got it fixed now. Thanks alot!

You probably accidentally auto-imported it when trying to use

java.util.Arrays
