Server won't start and seems to be caused by tinker's mod

Hi and thanks a lot for reading this !

I’m trying to start a Sky Factory 3 server but it returns me a bunch of errors, the main one seems to be caused by Tinker’s mod.

I’ve the whole crash report and on demand i can show you the log.

I’ll post the crash report just bellow because I don’t know how to make spoilers.

If you need more info, just ask.

Thanks a lot for your futur answers !

Please run java -version in the terminal for the server and post the output.

In the first time, thanks for your reply, before i was running on OpenJDK7 and now i’m with OracleJDK8

Here’s the return of the command java -version

java version "1.8.0_191"

Java™ SE Runtime Environment (build 1.8.0_191-b12)
Java HotSpot™ 64-Bit Server VM (build 25.191-b12, mixed mode)

Thanks again
