Hello,

I had the same problem. Probably you have an older Version of Java installed.
On my PC the old Version was installed in /usr/lib/jdk1.x.x. In /usr/lib there was a link called "java" pointing to the directory jdk1.x.x.
All I had to do was to install the new JDK in /usr/lib/jdk1.y.y, to remove the link (rm java) and to create a new link pointing to the new directory of the newer java version (ln -s jdk1.y.y java).
Since then it works fine.

Good luck.
