RubyConf 2024 Building JRuby: How We Implement Ruby on the JVM by Charles Nutter & Thomas Enebo

What does it take to build a language runtime on the JVM? This talk will show how we implement JRuby, from Java versions of core classes and native extensions to our parser, compiler, and JIT subsystems. You'll learn how to find and fix bugs, profile Ruby code, and integrate with the many libraries and features of the JVM.
