Why doesn Adhearsion support Ruby 1.9?
Adhearsion works with Ruby 1.8.x versions of Adhearsion (starting at 1.8.6) and JRuby 1.1 or later. JRuby has the distinct advantage of being able to run Adhearsion on the Java Virtual Machine, allowing you to use virtually any Java library in existence right in your Adhearsion application. The normal Ruby interpreter has fewer dependencies and is what’s generally used in Adhearsion applications at the time being.
