Recently, I have been trying to use mc forge 1.8.9 and it kept crashing on me. The game loads before quitting itself out. Here is the crash log: ---- Minecraft Crash Report ---- WARNING: coremods are present: SkyblockAddonsLoadingPlugin (SkyblockAddons-1.5.5-for-MC-1.8.9.jar) PatcherTweaker (Patcher-1.5.1 (1.8.9).jar) ModTweaker (Patcher-1.5.1 (1.8.9).jar) FMLLoadingPlugin (Skytils-0.1.1.jar) Contact their authors BEFORE contacting forge // Why is it breaking :( Time: 10/3/21 9:44 PM Description: Initializing game java.lang.NoClassDefFoundError: net/optifine/gui/GuiMessage at java.lang.Class.getDeclaredFields0(Native Method) at java.lang.Class.privateGetDeclaredFields(Class.java:2583) at java.lang.Class.getField0(Class.java:2975) at java.lang.Class.getField(Class.java:1701) at net.minecraftforge.fml.client.FMLClientHandler.detectOptifine(FMLClientHandler.java:277) at net.minecraftforge.fml.client.FMLClientHandler.beginMinecraftLoading(FMLClientHandler.java:191) at net.minecraft.client.Minecraft.func_71384_a(Minecraft.java:417) at net.minecraft.client.Minecraft.func_99999_d(Minecraft.java:329) at net.minecraft.client.main.Main.main(SourceFile:124) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) Caused by: java.lang.ClassNotFoundException: net.optifine.gui.GuiMessage at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:191) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 15 more Caused by: java.lang.NoClassDefFoundError: net/optifine/gui/GuiScreenOF at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:760) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:182) ... 17 more Caused by: java.lang.ClassNotFoundException: net.optifine.gui.GuiScreenOF at net.minecraft.launchwrapper.LaunchClassLoader.findClass(LaunchClassLoader.java:101) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 21 more A detailed walkthrough of the error, its code path and all known details is as follows: --------------------------------------------------------------------------------------- -- Head -- Stacktrace: at java.lang.Class.getDeclaredFields0(Native Method) at java.lang.Class.privateGetDeclaredFields(Class.java:2583) at java.lang.Class.getField0(Class.java:2975) at java.lang.Class.getField(Class.java:1701) at net.minecraftforge.fml.client.FMLClientHandler.detectOptifine(FMLClientHandler.java:277) at net.minecraftforge.fml.client.FMLClientHandler.beginMinecraftLoading(FMLClientHandler.java:191) at net.minecraft.client.Minecraft.func_71384_a(Minecraft.java:417) -- Initialization -- Details: Stacktrace: at net.minecraft.client.Minecraft.func_99999_d(Minecraft.java:329) at net.minecraft.client.main.Main.main(SourceFile:124) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at net.minecraft.launchwrapper.Launch.launch(Launch.java:135) at net.minecraft.launchwrapper.Launch.main(Launch.java:28) -- System Details -- Details: Minecraft Version: 1.8.9 Operating System: Mac OS X (x86_64) version 10.15.4 Java Version: 1.8.0_74, Oracle Corporation Java VM Version: Java HotSpot(TM) 64-Bit Server VM (mixed mode), Oracle Corporation Memory: 150452632 bytes (143 MB) / 335544320 bytes (320 MB) up to 2147483648 bytes (2048 MB) JVM Flags: 7 total; -Xmx2G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M IntCache: cache: 0, tcache: 0, allocated: 0, tallocated: 0 FML: Loaded coremods (and transformers): SkyblockAddonsLoadingPlugin (SkyblockAddons-1.5.5-for-MC-1.8.9.jar) codes.biscuit.skyblockaddons.tweaker.SkyblockAddonsTransformer PatcherTweaker (Patcher-1.5.1 (1.8.9).jar) club.sk1er.mods.core.forge.ClassTransformer club.sk1er.patcher.tweaker.ClassTransformer ModTweaker (Patcher-1.5.1 (1.8.9).jar) club.sk1er.patcher.tweaker.other.ModClassTransformer FMLLoadingPlugin (Skytils-0.1.1.jar) Launched Version: 1.8.9-forge1.8.9-11.15.1.2318-1.8.9 LWJGL: 2.9.2 OpenGL: Intel HD Graphics 5000 OpenGL Engine GL version 2.1 INTEL-14.5.22, Intel Inc.
