Hi, when I start my game with Bookshelfapi it crashes(does not look like the potion error).
The thing is, it only crashes on my Laptop, yes I tried different java versions :).

Here the Crash:

P.S.: Sorry if it's not bookshelfapi causing it. I'm very bad at crash-report reading!

Your using a very old version of Java 8. I recommend you update.

As its not working on the laptop, but it is on your other computer, this issue seems to be your java on the laptop

.okay, it still crashes. I use 1.8.0_73. But it looks like minecraft was using the "onboard" java before(the version that comes with the mc launcher)

It looks like you are missing some libraries from forge. Forge installs the scala library. Try reinstalling forge

No problem.

It started! Thank you soo much! I really need to learn how to read crash-reports :/.

Thanks!
