So I was installing Forge 1.12.2 when I noticed the launcher never opened. Instead it created a file I could open in notepad that said this: Exception in thread "main" java.lang.ExceptionInInitializerError at net.minecraftforge.installer.ClientInstall.getSponsorMessage(ClientInstall.java:401) at net.minecraftforge.installer.InstallerAction.getSponsorMessage(InstallerAction.java:60) at net.minecraftforge.installer.InstallerPanel.updateFilePath(InstallerPanel.java:334) at net.minecraftforge.installer.InstallerPanel.<init>(InstallerPanel.java:315) at net.minecraftforge.installer.SimpleInstaller.launchGui(SimpleInstaller.java:164) at net.minecraftforge.installer.SimpleInstaller.main(SimpleInstaller.java:51) Caused by: java.lang.ArrayIndexOutOfBoundsException: 1 at net.minecraftforge.installer.MirrorData.buildMirrorList(MirrorData.java:84) at net.minecraftforge.installer.MirrorData.<init>(MirrorData.java:63) at net.minecraftforge.installer.MirrorData.<clinit>(MirrorData.java:17) ... 6 more I've tried this with multiple versions to the same result, is there any way I can fix this?
