What can be wrong?
Lots of things, remember you are using Linux. Just a small list:
- Bad graphics driver
- OpenJDK instead of Sun JDK
- No JDK but only a JRE installed
- Forgot to recompile the kernel and make a raindance
Also, what exactly does “null” mean? Is that the error output? You get a NullPointerException? You get null output on the screen? Please be more specific.
In my first message is full output of installer. As you can see - it starts, looking for JDK, etc, etc… and oops! Finish.
