Server keeps crashing

[KruSion]

I made a really complicated tekkit server and everything works until I add one last thing.

First I installed the tekkit lite server 0.5.7 and then I let it load then I removed all the mods and the tree cap from the core mod...

Then I installed Bukkit Forge into core mods and till now the server runs okay.

Then I installed the following plugins into the plugins folder and changed the config and ran them and everything's working:

1. Chest Shop

2. ecoCreature

3. Essentials

4. iConomy

5. Jobs (not all features work here, the author says not everything is compatible with modloader or forge something like that)

6. Secure Chest

7. Vault

Then I installed the reason why I'm using tekkit tobegin with not simply bukkit:

Superheroes in Minecraft:

Then when I start the server I get crash errors:
