[1.7.10 - 1291] [EmasherMods] Server crash on startup

[grundyboy34]

Hi, I'm trying to get a server to run. It runs fine until I add the engineer's toolbox mod, and even fine if I remove the sockets from the mod. Normally I would just keep the mod out, but I'm not completely convinced the error is with the mod.

Here's the crash report.

If you look at this part, it seems that forge is causing the error? The mod is on github,https://github.com/Emasher/EmashersMods/tree/master/src/main/scala/emasher/sockets

What do you think, should I just remove the mod or is there a simple fix?

He's referencing a client-side only class when he's registering his message. Here's one example:

Thanks for the reply. I compared his current github code with my error and realized he must've updated the code. Seeing as his wikispaces died, I guessed that the jar he's providing for download isn't up to date with what's on the github. So I pulled the code and built it myself and it works just fine.

For anyone who has this problem, just download his repo from github as zip, extract, then use gradle to build. The new jar will be in build/libs
