Hi Michael, both, Chandra and Pascal, are right. Java 7 or higher is needed to run a snapshot of BaseX 8.0.
Since you're using Mac OS X and are (maybe) reluctant to update Java (as I can
see from your remarks ;-), another option for you could be to give BaseX.app
[1] a try.
It's packaged and prepared to run out-of-the-box on a Mac. And there is a
reason, why the package (as .tar.bz2) has 49M as compared to BaseX.jar with
3.3M - it has, among other things, jdk1.8.0_20.jdk included.
All the best
