Hi Luiz,

On a clean 14.2 system I get "command not found" for javac. Which of 
course makes sense.

I think the easiest solution for the SlackBuild is just to add 
"--disable-java" to the config and allow people to add it if they need to.

If there's no issues with that I'll go ahead and change it and re-submit 
(with a note in the README for the option to enable).

Thanks,

Barry
