Can't load modclass/corrupt jarfile/wrong java version

[HenryFBP]

Title: Can't load modclass/corrupt jarfile/wrong java version

Version: 3.1.2

OS: Ubuntu Precise Pangolin 12.04

Java Version: 7, 64-bit

Description of Problem:

I have only 64-bit java, this worked earlier too, when I run this code in a BASH script for Ubuntu:

#!/bin/bash

java -Xmx1G -Xms1G -jar Tekkit.jar nogui

read -p "Press [Enter] key to continue..."

I get the error log. Any suggestions? Reinstall java, get proper unzipper?

Error Messages:

See error log.

Make sure you only have Java 7, no other versions installed. The update your Java.

[HenryFBP]

Had Java 6, removed it. (thank you immensely, didn't need that version) Updated Java also. Error persists.
