`jruby_skip` is only available in ActiveSupport as its defined in [`abtract_unit.rb`](https://github.com/rails/rails/blob/master/activesupport/test/abstract_unit.rb#L33-L36). And caused  an `NoMethodError` exception when I tried to use it here.

if you know a way that  `jruby_skip` can be used in entire codebase, kindly let me know. I would happy to submit a  PR
