Eclipse won't start on first run.

[wozzinator]

I can't run eclipse on startup on this fedora machine (I use Ubuntu, but they only use Fedora in my universities lab which is the distro that i'm having the problem on.)

The text from /home/user/workspace/.metadata/.log :

Any help would be great so I can stop switching between Fedora and WinXP in the lab!

I think there is a problem using 64bit Java libraries, have you tried using EasyEclipse you just unzip and run.
