Exception: java.lang.ExceptionInInitializerError thrown from the UncaughtExceptionHandler in thread "main"

Apparently I'm either missing some files, or I messed up something.
Please Help!

I play forge on fedora 25 as well and I've had no issues so far, do you have the package java-1.8.0-openjdk installed?
Regards.
