For the past week of so, whenever I try to open any minecraft with forge, It wont open anything. I have been getting this message -------------------------------------------------------------------------- [16:48:46] [main/INFO] [LaunchWrapper]: Loading tweak class name cpw.mods.fml.common.launcher.FMLTweaker [16:48:46] [main/INFO] [LaunchWrapper]: Using primary tweak class name cpw.mods.fml.common.launcher.FMLTweaker [16:48:46] [main/INFO] [LaunchWrapper]: Calling tweak class cpw.mods.fml.common.launcher.FMLTweaker [16:48:46] [main/INFO] [FML]: Forge Mod Loader version 7.10.25.1208 for Minecraft 1.7.10 loading [16:48:46] [main/INFO] [FML]: Java is Java HotSpot Client VM, version 1.8.0_25, running on Windows 8.1:x86:6.3, installed at C:\Program Files (x86)\Java [16:48:46] [main/INFO] [LaunchWrapper]: Loading tweak class name cpw.mods.fml.common.launcher.FMLInjectionAndSortingTweaker [16:48:46] [main/INFO] [LaunchWrapper]: Loading tweak class name cpw.mods.fml.common.launcher.FMLDeobfTweaker [16:48:46] [main/INFO] [LaunchWrapper]: Calling tweak class cpw.mods.fml.common.launcher.FMLInjectionAndSortingTweaker [16:48:46] [main/ERROR] [LaunchWrapper]: Unable to launch java.util.ConcurrentModificationException at java.util.ArrayList$Itr.checkForComodification(Unknown Source) ~[?:1.8.0_25] at java.util.ArrayList$Itr.remove(Unknown Source) ~[?:1.8.0_25] at net.minecraft.launchwrapper.Launch.launch(Launch.java:117) [launchwrapper-1.9.jar:?] at net.minecraft.launchwrapper.Launch.main(Launch.java:28) [launchwrapper-1.9.jar:?] Java HotSpot Client VM warning: Using incremental CMS is deprecated and will likely be removed in a future release ------------------------------------------------------------------------------------------------------ Thank you, and hope to have it solved soon
