I believe you don't need to do anything along the lines of JRuby where you would sometimes need to bridge libraries from Java-land into Ruby.

This most likely makes the same assumption that you are using a similar kind of project management as in RubyMotion for iOS and using RM specific libraries.

I've never had the opportunity to bridge Java-to-Ruby for JRuby. But when I read "the runtime uses JNI", I read that as a bridge.

And when they start off with "Ruby classes are Java classes", then later say "everything is compiled to native" that seems like more double-speak.
