JavaZone 2010 - How JRebel works?
JRebel came out as a class reloading tool in 2007, with a promise to save your time by skipping redeploy. Since then we have delivered on that promise, and then some, and JRebel has grown to a large project with hundreds of thousands of line of code. In this talk I'll reveal the basic principles that JRebel uses to skip builds and redeploys and show you some of the code doing the work. I'll also speak about some of the (unique?) challenges that our team had to face and how we solved them.
