JRuby: Ruby for the JVM
summary
JRuby implements Ruby 1.8 on the JVM with a full 1.8 compiler that emits Java bytecode and an interpreter that falls back to JIT, ships a 1.0.2 release that fixes 99 bugs fixed, and demonstrates a Fibonacci benchmark halving runtime with inline method caching (about 1.2s to ~0.6s). Core classes use Java with annotations, parser is a Java port used by IDEs, threads are native threads, objectspace is disabled by default for performance, and Rails runs via JDBC with Warbler/GlassFish deployment.
