This is fantastic. I know a lot of programming languages and I love them all for different reasons, but I think I am most productive and most likely to produce error-free programs in Java. All the verbosity that people hate is a feature to me, I know exactly what my program is doing.

However, I have done 95% of my web development in Ruby due to the Sinatra and Rails frameworks. The developer experience is too good to ignore. I'm hoping this can replace my Sinatra use case ... I don't think the magic of Rails could ever be replicated in Java.
