Does that demo work for you on a Mac? I just tried it with the previous
7.0 release and had the same results. My Java version is 1.8.0_91, 64
bit. If it does work for you, would you mind posting your lib folder
somewhere so I can see if it's a compilation/configuration issue on my end?
Thanks,
Kevin
