I looked at this and seriously have no idea as to what could be causing it. The error claims the file JewelrycraftMod is missing, which is false, because if it were true everybody would be having the same issue.

[igoutta]

Why the fml load darkknight.jewelrycraft.JewelrycraftMod but the class have only this package darkknight.jewelrycraft;

[sor1n]

Oh wow, I think I might know the problem. You should probably have forge installed, nobody uses FML anymore. Dunno if that really is the problem, but please try it.

[igoutta]

I have Forge installed (1403), I did an experiment: replace the class of 1.0.9 with the old 1.0.8, but the problem still remains, now I know the problem it's in the new code. I'm using the 1.0.8 (laggy) and works perfectly.

[sor1n]

Can you try it with the curse launcher or normal Minecraft launcher and tell me if it does the same thing? Because I tested it with those and it should. I have also tested using MultiMc and it worked just fine. I had created a new instanced with same forge version as you and added my mod and everything was fine. I assume the problem relies on another mod, not mine.

Note: I am pretty sure you aren't supposed to have both FML AND Forge installed at the same time. Please remove FML and try again.

Sor1n, it looks like you built the mod for Java 8, while igoutta is running Java 7 from MultiMC, which doesn't automatically use Java 8 like the vanilla launcher.

[igoutta]

Interesting.

[sor1n]

Ok then, so update to Java 8, please :3 Also I thought Java 7 is compatible with Java 8, but I guess not.

[sor1n]

I'm going to close the issue if Java 7 was the problem. Just use Java 8 and everything will be fine.

Last comment: Edit in curseforge the avalaible versions of Java for the file, that's was the first problem in fact.

[sor1n]

Ok ;)
