Had the same problem, and found the solution in another thread...

Update Java to version 7...

I'm running on Linux and it worked for me :)

[Owen]

Hi, thanks for the reply, unfortunately, I don't fully understand how to install java 7 on my Linux centOS, I would really appreciate it if you could send a tutorial or something my way. :-\

[Stampe77]

I'm no Linux expert, so I google 8)

First hit on "install java 7 on my Linux centOS" (copied from your post)

http://www.if-not-true-then-false.com/2010/install-sun-oracle-java-jdk-jre-7-on-fedora-centos-red-hat-rhel/

Hope it helps

Java won't fix this, the Tekkit release itself was broken.

Which you would have seen if you looked at the stickies.

[Goz3rr]

Updating your java does fix this error. There are just some ID Conflicts and other bugs in Tekkit itself (Crash on placing BC engines etc)
