Hi everyone, I'm having a problem executing Eclipse Juno on Fedora 16. First of all, I followed this tutorial for the installation

Install Eclipse SDK 4.2 (Juno) on Fedora 17/16, CentOS/RHEL 6.2/5.8

I did everything on the tutorial, but when I type eclipse or /opt/eclipse/eclipse on the terminal, I got an error:
Java Code: 
Eclipse:
An error has occurred. See the log file
/opt/eclipse/configuration/1342403831992.log.
And here is what is in the file it generate:

Just in case you want to know, when I type java -version I get this:

java version "1.7.0_05"
Java(TM) SE Runtime Environment (build 1.7.0_05-b06)
Java HotSpot(TM) Server VM (build 23.1-b03, mixed mode)

I really will apreciate any suggest, I'm getting crazy with this.

Thanks you in advance.
