Posted September 1, 201312 yr So, I am running Minecraft on my mac and I installed forge on my client using the installer no problem. My friends and I wanted to play a modded survival together so I made a server (running the jar using start.command and everything, so I could connect to it and it was playable) and then used the same installer to install forge on the server (I used the folder in which the server files were). Then i doubleclicked the forge server jar file and it made the mods folders, libraries, etc. Then I replaced the minecraft server jar in the start.command with the forge file and ran it again. It got somewhat far and then I got this error: Last login: Sat Aug 31 20:10:21 on ttys000 /Users/johnsimpson/Desktop/Troy\'s\ Saved\ Stuff/minecraft\ server/start.command ; exit; new-host-3:~ johnsimpson$ /Users/johnsimpson/Desktop/Troy\'s\ Saved\ Stuff/minecraft\ server/start.command ; exit; Aug 31, 2013 8:20:52 PM net.minecraft.launchwrapper.LogWrapper log INFO: Using tweak class name cpw.mods.fml.common.launcher.FMLServerTweaker 2013-08-31 20:20:52 [iNFO] [ForgeModLoader] Forge Mod Loader version 6.2.57.845 for Minecraft 1.6.2 loading 2013-08-31 20:20:52 [iNFO] [ForgeModLoader] Java is Java HotSpot 64-Bit Server VM, version 1.6.0_51, running on Mac OS X:x86_64:10.6.8, installed at /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home 2013-08-31 20:20:52 [iNFO] [sTDOUT] Loaded 39 rules from AccessTransformer config file fml_at.cfg 2013-08-31 20:20:52 [iNFO] [sTDOUT] Loaded 107 rules from AccessTransformer config file forge_at.cfg 2013-08-31 20:20:54 [iNFO] [ForgeModLoader] Found valid fingerprint for Minecraft Forge.

Stuff/minecraft server/./crash-reports/crash-2013-08-31_20.21.01-server.txt I also tried running the minecraft server jar in the start.command and it just launched without forge. Can anyone help me with this problem?
September 1, 201312 yr If not, update to java 7. Read the EAQ before posting! OR ELSE! This isn't building better software, its trying to grab a place in the commit list of a highly visible github project. www.forgeessentials.com Don't PM me, I don't check this account unless I have to.
September 1, 201312 yr Author Looks like your Java installation is broken. Especially the ZipFile class. How do you think that I should go about fixing this?
September 4, 201312 yr Update to 9.10.0.846+ It was a small Java 1.6 incompatibility cpw introduced, an then fixed once he was made aware of it. However, I do advise you update to java 7 simply because of the major security and performance improvements it has. I do Forge for free, however the servers to run it arn't free, so anything is appreciated. Consider supporting the team on Patreon
