I am launching the server with forge 1.12.2 latest and have followed many tutorials on how to install it and it seems to be working fine for them but not me. I would very grateful if someone were to help me, thanks! Here is what is displays in console on server startup! 10.01 01:29:46 [Multicraft] Starting server!10.01 01:29:46 [Multicraft] Loaded config for "Custom.jar (Use and upload your own JAR)"10.01 01:29:46 [Multicraft] Updating eula.txt file10.01 01:29:46 [Server] INFO A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException10.01 01:29:46 [Server] INFO at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method)10.01 01:29:46 [Server] INFO at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)10.01 01:29:46 [Server] INFO at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)10.01 01:29:46 [Server] INFO at java.base/java.lang.reflect.Method.invoke(Method.java:566)10.01 01:29:46 [Server] INFO at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:70)10.01 01:29:46 [Server] INFO at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:34)10.01 01:29:46 [Server] INFO Caused by: java.lang.ClassCastException: class jdk.internal.loader.ClassLoaders$AppClassLoader cannot be cast to class java.net.URLClassLoader (jdk.internal.loader.ClassLoaders$AppClassLoader and java.net.URLClassLoader are in module java.base of loader 'bootstrap')10.01 01:29:46 [Server] INFO at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34)10.01 01:29:46 [Server] INFO at net.minecraft.launchwrapper.Launch.main(Launch.java:28)10.01 01:29:46 [Server] INFO ... 6 more10.01 01:29:46 [Multicraft] Server shut down (starting)10.01 01:29:46 [Multicraft] Restarting crashed server in 5 seconds10.01 01:29:46 [Multicraft] Looks like a crash, check the server console.
