Beyond Bytecode: What happens to your code at runtime? with Charles Nutter

Whatever language you use on the JVM, it eventually gets compiled down to bytecode and executed. But what exactly happens to bytecode after it starts running? This talk will take a deep dive from Java source through bytecode and into the wonderful world of the JVM JIT compiler, exploring how code is analyzed and optimized for the host CPU. We'll start with a basic primer on JVM bytecode and then watch its progress as it flows through the JVM using standard, open-source tools.
