JRuby Everywhere! Server, Client, and Embedded
summary
JRuby claims concrete wins: the red/black benchmark runs almost twice as fast as CRuby with a C extension, JRuby 9.1.6 ships and aims for Ruby 2.4 compatibility, and ActiveRecord JDBC is rebooted to reuse ~75% of Rails code and hits 99.57% of Rails tests on SQLite. Demos show calling Java libs directly (Purugin Minecraft plugin), JRubyFX and FXML GUIs, executable JAR/war packaging, Docker/Heroku deployment, and Raspberry Pi embeds; caveats include a native-extension loader bug in 9.1.6 and a ~70MB memory footprint.
