When i try to boot up my forge 1.12.2 14.23.5.2859 server through bat or cmd i keep getting an error. However it boots up fine when i just click the .jar file (with the main concerning disadvantage being that i don't know how to specify RAM in that way. It just defaults to 1Gb resulting in shitty performance) D:\MinecraftServer\ModpackServer>java -Xmx4096M -Xms4096M -jar forge-1.12.2-14.23.5.2859.jar nogui 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:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:568) 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 D:\MinecraftServer\ModpackServer>PAUSE Press any key to continue . . . ^ this was with a bat file containing java -Xmx4096M -Xms4096M -jar forge-1.12.2-14.23.5.2859.jar nogui PAUSE and yes, the jar file name is correct i've checked it multiple times This is what is in my Java folder, if that is of any help Thanks in advance
