            *******************************************************************************
            The shoes-swt backend requires a 9.X version of JRuby.

            You are running the following Ruby instead:

              #{RUBY_DESCRIPTION}

            Please download JRuby from http://jruby.org (or your favorite Ruby version
            manager), then check our https://github.com/shoes/shoes4#installing-shoes-4 to
            get Shoes installed.

            Sorry for the inconvenience!
            *******************************************************************************
