So, I am trying to host an FTB Revelation server, version 3.4.0. The problem is that every time I try to start the server, it gives me the following error:
A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException

I tried using the .bat file, the .jar file and even the console, all of wich failed. Am I doing something wrong?
