**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 .

After the screening, let’s chat about the film’s visuals, themes, performances, or anything else that resonates with you. Date: Saturday, 13th June 2026 Time: Film starts at 2:00 PM, let's meet at 1:45 PM Venue: Filmhouse, Golden Mile Tower, 6001 Ticket booking link: https://filmhouse.sg/filmhouse-singapore/booknow/949/ We look forward to seeing you there, come for the film, stay for the conversation.

**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!

**Friday is our open co-working day.** ​​Friday is our open co-working day. Arrive anytime from 10AM — bring your laptop, grab any open seat, stay as long as you like. ​Most people show up after lunch and settle in before The Stage. It's quiet, focused, and builder- and founder-led. **The Stage @ 1.30pm: Demo Day!** Sign up for demos here: [https://www.notion.so/sq-collective/Demo-Day-The-Stage-303aae2f95ae80a78560c0502ee8ff6b?source=copy_link](https://www.notion.so/sq-collective/Demo-Day-The-Stage-303aae2f95ae80a78560c0502ee8ff6b?source=copy_link&utm_source=luma) This week is Demo Day. ​​Everyone gets 5 minutes to share what they are building. ​​If you are new, this is your chance to show what you are working on now. If you have presented before, come back and show how the project has changed since the last time. ​​The point is not polish. It is progress. Show the work as it is, share what has changed, and let the room see the build happening in real time. ​After the session, we go back to work.

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

Over a billion documents processed. Millions of Veterans impacted. Hundreds of thousands of employee hours saved. Faster decisions. Greater accuracy. More benefits in the hands of our disabled Veterans. We created Smart Search, the world’s largest consumer of Amazon Textract, right when GenAI began reshaping what’s possible. Since then, we’ve built a suite of AI‑driven solutions that transform this data into real, measurable outcomes—accelerating benefits decisions for our Nation’s Veterans. Join us for a focused conversation on how an outcome‑driven approach to AI is helping us boost accuracy, streamline workflows, and deliver faster results for those who have served. This is a follow up to the AWS re:Invent 2023 "Intelligent Document Processing with Gen AI for Public Sector" presentation.
