!jruby test filter broken
Created by: kaiwren
drb_command_line_spec.rb is currently failing on JRuby 1.6.0 because the describe "::DRbCommandLine", :ruby => "!jruby" directive isn't respected. Changing these lines in spec_helper.rb when "!jruby" RUBY_ENGINE != "jruby" to when "!jruby" RUBY_ENGINE == "jruby" fixes it.
