Mastering Java bytecode with ASM

At first sight Java bytecode can seem an obscure piece of low-level magic. But there are tons of open-source Java frameworks in the wild that do bytecode instrumentation and all kind of magic. What if you’d like to contribute or fix a bug? Understanding Java bytecode may appear quite helpful once you have to solve problems that are related to binary weaving of Java classes, and some things you can do are just plain freakin' cool. This talk will introduce you the JVM and bytecode basics using live coding demo with ASM (http://asm.ow2.org/) and creating a cool application live.
