JRuby: What, Why, How... Try It Now
summary
JRuby 1.5 ships after 1,500 user-reported bug fixes and ~3,000 revisions since last year and claims microbenchmark-leading performance by leveraging the HotSpot JDK optimizations and GC. Ruby 1.9 features run via a 1.9 runtime switch (fibers, new parser, Oniguma port), demos include a JMonkey-engine game calling Java libraries directly, and deployment is one-command via the glassfish gem. Thread-safe Rails 2.2 on JRuby cuts per-app heap from ~3.3MB to ~0.5MB in tests. FFI works cross-implementation (callbacks, qsort, PTY bindings).
