Hello all,

My friend has been having problems loading modpacks that have the mods Mekanism and SAPManPack (Clay Soldiers). Whenever he finished loading the modpack, and played it, it immediately crashes with the error:

  1. java.lang.UnsupportedClassVersionError: mekanism/common/asm/LoadingHook : Unsupported major.minor version 51.0

(This is the crash for mekanism but it is the same thing for SAPManPack)

He is running Java 7 and 8 to make sure both work, but neither did. We do not know why it is doing this, can someone please help?
Thanks, Gunner

We used 2 separate modpacks, and 1 had Clay Soldiers (GMM Lite) and 1 had Mekanism (Gunner's Mechmagical Modpack). Both were the same error.
GMM: http://www.technicpack.net/modpack/gunner-mechmagical-modpack.658517

GMM Lite: http://www.technicpack.net/modpack/gmm-lite.669463

GMM Lite Crash: http://pastebin.com/qPRGvxzr

These are not actual crash reports, since he cannot generate crash report files since the second he loads the modpack it crashes. These are logs with the crash in them.

If you also just want a direct download link of the pack I can provide that too.

Directly from the log you provided:

[17:49:01] [main/INFO] [FML/]: Java is Java HotSpot(TM) 64-Bit Server VM, version 1.6.0_65, running on Mac OS X:x86_64:10.9.5, installed at /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home

Note that it explicitly shows JDK 1.6 (i.e. Java 6). This won't work. Must be 1.7 (i.e. Java 7) or higher, preferably Java 8.

My friend installed Java 7 and 8 and neither worked, each with the same error.

It wouldn't really be necessary to send logs because they just say the same exact thing

My friend tried to check his logs but the only items there were fml-client logs. He tried loading the Modpack again but it did not generate a log with the date as the name.

Nvm, we tried switching between Java versions and uninstalling/reinstalling the modpacks and even the launcher and eventually it worked. Thanks for your time!

Actually, we are having some new problems when the modpack loaded. When he tried to join, on the server it said he joined the game, however on his screen it was the blank dirt screen. After a minute he disconnected, with the disconnection log looking like if a person logged out, but on his screen it is still blank. Eventually it turned into a black screen and crashed. When he tried to make a single player world, a regular default world said "Shutting down internal server" after building terrain, and super flat never loaded after building terrain. Are there ways to fix this?
