[1.5.2] Not sure why my server crashes on startup. Help?

[starwalker5534]

For some reason, I can't start up my server with any kind of mod. Regardless of the type of mod.

Here's the crash report

I think I might have installed something wrong, but I'm fairly sure I did everything correctly? I know this might be a stupid reason that I'm overlooking, but I really need some help here  :'(
