Bug description:
I'm trying to use gephi on a debian lenny system.

I have the official sun java 1.6 jdk installed on my system:
gully@gully:~/Desktop/gephi-0.6-beta3.linux.i586$ dpkg --get-selections | grep java6
sun-java6-bin                                   install
sun-java6-jdk                                   install
sun-java6-jre                                   install

Then when I'm trying to run gephi, I got this error:
gully@gully:~/Desktop/gephi-0.6-beta3.linux.i586$ ./gephi.sh
Exception in thread "main" java.lang.UnsupportedClassVersionError: Bad version number in .class file

My JAVA_HOME is :

gully@gully:~/Desktop/gephi-0.6-beta3.linux.i586$ env | grep JAVA_HOME
JAVA_HOME=/usr/lib/jvm/java-6-sun

Did I miss something in the installation process ?
