> Regarding Rhino, you got to make sure the ruby rhino with latest GitHub - mozilla/rhino: Rhino is an open-source implementation of JavaScript written entirely in Java It looks pretty silent there Commits · cowboyd/therubyrhino · GitHub . Ideally I would prefer v8, but at a minimum we would want latest Rhino.

_therubyrhino_ should just work, if not there’s a pretty solid attempt to use the engine provided with Java 8,  
which is kind of a (direct) successor of Rhino, `gem 'dienashorner', platform: :jruby` … really depends what the JS engine is used for - if mostly for compiling with the asset pipeline than both are expected to work fine.

have also looked into _xorcist_, managed to run into one issue - not failing properly on frozen strings, but its pretty edge case that is easy to work-around + PR submitted.
