Hi, I'm interested in contributing to JRuby, particularly on interpreter / compiler / runtime improvements. I found [this post], and I think I would like to start off with optimizing the interpreter. If you guys have any specific pointers, that would be nice; otherwise I'll just start poking around with a profiler.
About me: I'm a college senior now. I used to work on Doppio, a JVM in TypeScript, so I know my way around the JVM spec. I've also written a couple of tools that use the ASM bytecode library. JRuby seems like a good next step :) Jez [1]: http://ruby.11.x6.nabble.com/GSoC-2014-tp4997488p4997499.html
