JRebel under the covers - how is it even possible?


java Java SE

Room 4A - Metrosoft

Monday at 12:20 - 13:20

This talk presents a number of conceptual and technical challenges that we discovered while building JRebel. At first, the JVM wasn't designed for live updates, so we will talk about the engine that mitigates the problem. Secondly, the diversity of Java ecosystem, created by the variety of application servers, the frameworks and tools, makes it challenging in creating a generic solution that would fit the majority of developers. We will see, how Java platform itself allows us to develop a solution by applying bytecode instrumentation mechanism.

JRebel does live code reloading to ensure that the developer can keep instantly alternating between the developing environment and the web browser, to save wasted time and increase the productivity flow.
