Josh (@starbuxman) has been the first Spring Developer Advocate since 2010. Josh is a Java Champion, author of 7 books (including "Reactive Spring") and numerous best-selling video training (including "Building Microservices with Spring Boot Livelessons" with Spring Boot co-founder Phil Webb), and an open-source contributor (Spring Boot, Spring Integration, Axon, Spring Cloud, Activiti, Vaadin, etc), a Youtuber (Coffee + Software with Josh Long as well as my Spring Tips series ), and a podcaster ("A Bootiful Podcast").
Spring Boot 4.x and Java 25 have arrived, making it an exciting time to be a Java developer! Join me, Josh Long (@starbuxman), as we 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.
It's that time of the year gain! Devoxx time! And we love being here. But you know which place we love even more? Production. And we don't know anything that makes it easier to survive and thrive in production than Spring Boot 4 and GraalVM!
In this session, join us - Oracle Vice President and GraalVM benevolent dictator for life Thomas Wuerthinger and his trusty sidekick, Spring Developer Advocate Josh Long - and we’ll look at some of the amazing ways that Spring Boot 4 and GraalVM are an insurmountable win for your JVM applications in 2026, to say nothing of your Python and WebAssembly applications! Experience blazingly fast startup, better security, and lower footprint for greener and cheaper production deployments!

Cult.Repo — the team behind cinematic documentaries on React, Node.js, Kubernetes, and more — brings its latest film to Devoxx UK for its world premiere.
Spring traces the full arc of one of open source's most consequential projects: from its origins as a quiet rebellion against enterprise Java complexity, through the paradigm shift of Spring Boot, into the microservices era and the cloud-native architectures that now run beneath some of the world's most critical software.
It's a story about technical vision, community, and what it takes to stay relevant across two decades of relentless change.
After the film, there will be a panel featuring Josh Long, Marit van Dijik, and Steve Poole.
Doors open at 6:30pm
Film starts at 7pm
