It may just be my imagination but some of the code that was posted in a preview thread looked like C# to me. Of course, for the Mac this wouldn't work (unless the Mono Framework was pre-installed, and even then..)
My query was really what programming language are you using? I'm guessing Java but I couldn't 100% confirm this from what I had read, though it does seem likely.
Just idle curiosity
EDIT: Meh answered my own question; seems it is.
