I might be wrong, but I think Forge is the coremod that is crashing, as there are no coremods specified in the "coremods are present:" warning.

 

Also, the crashreport contains this:

 at java.lang.Class.getDeclaredFields0(Native Method)
   at java.lang.Class.privateGetDeclaredFields(Unknown Source)
   at java.lang.Class.getField0(Unknown Source)
   at java.lang.Class.getField(Unknown Source)
   at net.minecraftforge.fml.client.FMLClientHandler.detectOptifine(FMLClientHandler.java:297)

It looks like the coremod to detect optifine hasn't been updated yet?

 

@OP, what Forge version are you using?

[diesieben07]

It's crashing because the class

Config

(no package), which is part of Optifine, has invalid bytecode.

 

So: this is Optifine's fault, most likely because a wrong version was installed.
