This is your entire log?  Update Java to 8 first, then we'll talk.

This is a case of a mod for an incorrect minecraft version.

[Torezu]

Good to know.  Would still being on Java 7 have anything to do with it either?

That would depend on the version of minecraft used, but if Java 7 was an issue, you'd have a nice major.minor version 52.0 error. 52 = Java 8. I've seen errors for 51 and 50 as well. Yes. 50 is Java 6. Person was running Java 5.
