Massive Error D:

Hello I need some help,
I'm having this error in my console :
http://pastebin.com/FZxpWxbc
I Think it might be multiverse,but here are my plugins :
[INFO] Plugins (39): BeTheMob, Orebfuscator, StreetLights, WorldEdit, TotalEconomy, AntiBot, BukkitCompat, Buycraft, Vault, PlayerHeads, PermissionsEx, LWC, uSkyBlock, TreeAssist, WorldGuard, AntiGrief, AutoMessage, BukkitAnnoyances, CensorNizer, Lockette, ClearLag, Modifyworld, BanVote, SupplySign, Votifier, MobArena, GAListener, Essentials, Citizens, EssentialsSpawn, PlotMe, Builder, EssentialsChat, Multiverse-Core, AuthMe, Factions, Multiverse-Portals, Multiverse-Inventories, Multiverse-NetherPortals
They are all updated to the latest version (Build for Multiverse)

 

You'll have to restart your server, you have just experienced one of the limitations of your OS/distribution

 

Ubuntu,ok...
I'll require to install CentOS
