**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!

**Talk Abstract:** — \# Bootiful Spring Boot 4: Sweet and Sour Spring Boot 4.x and Java 25 have arrived, making it an exciting time to be a Java developer! Join us, **Josh Long** (@starbuxman) and **DaShaun Carter** (@dashaun), will dive into the future of Spring Boot with Java 25. We'll learn how to scale your applications and codebases effortlessly, explore the robust Spring Boot ecosystem featuring AI, modularity, seamless data access, security, and cutting-edge production optimizations like Project Loom's virtual threads, GraalVM, AppCDS, and more. Let's explore the latest-and-greatest in Spring Boot to build faster, more scalable, more efficient, more modular, more secure, and more intelligent systems and services and we'll look at how to get older apps to this leaner, greener future. \-\-\- **Josh Long** (@starbuxman) has been Spring's first-ever Developer Advocate since 2010. A Java Champion, author of 7 books, host of *A Bootiful Podcast*, and open-source contributor — if Spring ships it, Josh has probably already done a live demo of it. **DaShaun Carter** (@dashaun) is a Spring Developer Advocate at Broadcom, Testcontainers Champion, and keynote speaker with a passion for helping developers ship better software, faster. Whether he's on stage, on a Raspberry Pi, or on a racecourse, he brings the same deliberate, high-energy focus to everything he does. **Important:** Please share your mail address ( if you have not done already) , need it for security clearance at Redhat .

Extensions allow developers to customize the editor with new features, integrations, and workflow improvements tailored to their needs. In this session, we’ll cover what extensions are and the different types available, including full extensions written in TypeScript or JavaScript, along with lighter-weight extensions such as color themes, language packs, language support, code snippets, and keymaps. We’ll also look at practical reasons a developer might create an extension, from automating repetitive tasks to adding custom tooling. The session includes a hands-on walkthrough of creating a new extension, testing it locally, and understanding the basic project structure. We’ll close with a brief overview of how extensions are packaged and published to the Visual Studio Marketplace and other distribution options. **YouTube Link** TBD
