I would like to point out that I am having the same problem when using the latest version of forge in eclipse with and empty mod (except for the @mod data).
Here is a pastebin of my FML log: http://pastebin.com/6A7Fyzqz
I hope there is a way around this, because I was hoping to have another look into modding tonight, but I might have to stop early by the look ok things
EDIT: I have found the error in my code. I hadn't added a pre-init class yet and adding one fixed the problem. Though it is unlikely that the other mods don't have a pre-init method, there could be something wrong with it that is causing the problem. Please not that I am not sure, since my knowledge of modding is basically 0.01
