Who should be doing these fancy optimizations anyway? — Fredrik Öhrström
JRuby, Jython, etc., transform a source language to bytecodes for the JVM. What kind of optimizations should they do (or not do) before handing the bytecode to the JVM? I will present a few anti-optimizations on bytecode to demonstrate what the JVM can handle and what it cannot handle. It will be visualized using JRockit with a peep hole into the JRockit optimizer.
