**About the Speaker** **Simon Ritter** With over a decade of experience as Deputy CTO at Azul Systems, our speaker has helped shape the adoption of Java and JVM technologies across the global developer community. A recognized expert in Java and open source, he is passionate about advancing developer productivity, application performance, and innovation throughout the software ecosystem. **Agenda** **Keeping Your Java Hot by Solving the JVM Startup and Warmup Problem** Java bytecodes and class files deliver on the original vision of “write once, run anywhere”. Using a Just-in-Time (JIT) compiler allows JVM-based applications to compile only the code that’s used frequently and optimise it precisely for how it's used. Using techniques like speculative optimisation can often deliver better performance than static, Ahead-of-Time (AOT) compiled code. However, this flexibility and performance come at a cost. Each time the JVM starts an application, it must perform the same analysis to identify hot spots in the code and compile them. This is referred to as the application warmup time. In this session, we’ll look at several approaches to alleviating or even eliminating this problem. Specifically: · Static compilation of Java code ahead-of-time (AOT). Specifically, the Graal native image approach · Generating a JIT compiler profile of a running, warmed-up application that can be reused when the same application is restarted, eliminating the need for much of the JIT compilation. This will include details of the work of the OpenJDK Project Leyden. · Decoupling the JIT compiler from the JVM for a Cloud environment. Providing a centralised JIT-as-a-Service allows caching of compiled code and offloading the compilation work when new code must be compiled. · Creating a checkpoint of a running application. This includes all application state (heap, stack, etc.) in addition to the JIT-compiled code. Project CRaC will be used as an example. At the end of the session, you’ll be all set to keep your Java hot! **Modern Java Puzzlers** Since JDK 9, Java, as a language, has evolved faster than at any point in its 30-year history. For developers, this is great, as it means we get more new features that make our code more concise and, hopefully, easier to read and understand. All new language features also bring their quirks and possibly unseen consequences. In this fun interactive session, we’ll examine a range of recent language features and pose questions to the audience about how the code works and what it does. We’ll cover many of the new language features from recent releases, including switch expressions, sealed classes and pattern matching. We’ll even look at some curious ways special characters can be used in unexpected ways. The answers will most definitely not always be as you expect!
