Description of Problem:

I have no plugins installed. The only problem is, netherore is not working. When i launch, it just creates all these errors, and the server just crashes there. I removed netherore and it worked. But the problem is i need netherore and it is crucial to my server.

Although, you say you have Java 7, maybe you have more than one Java version and the wrong version is being used for tekkit server.

I got that error in Linux when using openjdk-6 unless I disabled nether ores (by renaming mod_NetherOres.jar to different file extension). After removing openjdk-6 and installing openjdk-7 and renaming that mod back to a .jar, everything worked (including client). I am sure that I have seen posts related to Mac about getting tekkit server working with Java 7 and client with Java 6 (not sure why Java 7 would break Mac client).
