Solved Exception in server tick loop

[call_your_mother]

Hello, I am unable to start a fresh FTB Lite Server.
Downloaded, unzipped and startet but got this Error:
http://pastebin.com/FS1JYHWh

• What OS are you running? - Windows 7 for Client and Server
• Are you using minecraft hosting provider or a dedicated/local server not designed for minecraft? - Local Server
• What version of FTB are you using? (Dont just say latest tell us the version) - FTB Lite (v1.2.3) Minecraft Version 1.4.7
• Did you add any mods to the server pack? - No, it is the untouched Server
• What are your server specs? - i5-2500k and 1GB allocated RAM

Hopefully anybody can help me with this
And sorry if my English is not that good, but I'm not a native speaker

Looks like you have inventory tweaks on the server. Its client side only.

Thank you, if I delete all the inventory tweaks stuff from the Server it works.

But I don't get why this is happend, it's the origininal server from the download site.
