So I reinstalled Java 8 again and the problem still persists. Is there a way you can help me do what's needed to be done? Do I need to change what's written in the start.command?

Unfortunately, I do not know how to uninstall Java 9 at the moment, but here's a screenshot of my current version of Java:

I do not currently have my laptop with me right now, but yesterday I just checked the Java version on my Mac via the System Preferences and it said that I was using Java 8u221. But if the log said that I am still using Java 9, I'll try to uninstall that version once I can have access to my laptop ASAP and send another update from you guys. Hopefully this will fix the problem.

I already have said above that I recently installed Java 8. Problem still occurs.

Hi, I am trying to create a modded Minecraft Forge server so I could play with my friends. I watched every video on how to make a modded Minecraft server using Forge on a Mac and they do not seem to have any problems at all, but unfortunately the terminal can not run the forge jar and is giving me error messages which will be provided below. The reason why I prefer using the terminal instead of the provided Minecraft server jar provided by the official Minecraft website is because the SpongeForge mod disables the GUI as far as I know. But anyways, here are the information: I am currently using a 2018 Macbook Pro 15. Specs: CPU 2.2 GHz Intel Core i7 RAM 16GB 2400mHz DDR4 GPU Radeon Pro 555X 4GB Intel UHD Graphics 630 1536 MB I also installed the recommended Java version - Java 8 Update 221. Here's what's inside my start.command #!/bin/bash cd "$(dirname "$0")" exec java -Xms1G -Xmx1G -jar forge-1.12.2-14.23.5.2838-universal.jar nogui and Here's the log on my terminal when i try to run the start.command: Last login: Thu Jul 18 00:22:03 on ttys000 Keiths-MacBook-Pro:~ keithphilippe$ /Users/keithphilippe/Desktop/Modded/Server/start.command ; exit; A problem occurred running the Server launcher.java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:567) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.run(ServerLaunchWrapper.java:70) at net.minecraftforge.fml.relauncher.ServerLaunchWrapper.main(ServerLaunchWrapper.java:34) 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') at net.minecraft.launchwrapper.Launch.<init>(Launch.java:34) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) ... 6 more logout Saving session... ...copying shared history... ...saving history...truncating history files... ...completed.
