    *******************************************************************************
    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!
