I get an instant error while trying to launch any of the .sh :

$ sh hax-tutorial.sh

Issue fixed, by downloading and installing my-self the latest JDK and JRE.

Also, (I'm on a Mac) I add to manually replace the CurrentJDF link from /System/Library/Frameworks/JavaVM.framework/Versions/ to "refresh" the version from the terminal.

Hello and welcome to the group.
Nice to hear you got things sorted out. Indeed, Hax requires Java 7 or higher (JRE should be sufficient).
You are also the first person I know of running Hax on a Mac. I myself have no means to test it on a Mac, so I was not sure whether it would work.
Please post any other issues or oddities you encounter.
Cheers
