JRuby: Not Just Another Ruby Implementation
summary
JRuby aims to run real Ruby apps on the JVM and demonstrates concrete results: passes 98% of Rails unit tests, jruby-complete single-jar distribution for easy deployment, native JVM threads and Unicode support so threads run on multiple cores and strings interoperate with Java, and a compiler/JIT that already shows 1.5–2× speed on compiled shootout tests versus MRI while interpreted mode sits around half the speed but steadily improves.
