You are running a client-side only mod in the server, it tries to find "minecraft.jar" when it doesn't exist on the server, as seen here in the crash report:

Caused by: java.lang.ClassNotFoundException: net.minecraft.client.Minecraft

 

I had this same experience with Flans back in the day if you don't have the required packs then as soon as you place any entities from that mod you crash not only the games but the server. Make sure every person has all the right mods/mod versions and that visual mods like better-foliage are only on the client.
