Server pack will not start

[Koekje]

Hi there,

I am trying to make a server for the latest version of Create Flavored (5.10). After installing and extracting the server pack to a folder, I ran the SERVER-START.bat file and agreed to the EULA. At some point something went wrong, without much knowledge of modpacks I tried to find the solution, what went wrong could be that I may have had the wrong version of JDK/jre Java or some of the mods in the modpack are resulting in some errors. I tried to remove the rottencreatures mod, as it seemed like that was the problem, but this only resulted in a few errors going away and I still was not able to start up the server. So now my question is: What java versions should I use and/or is there a solution to my code below?
