Devoxx UK 2026 is running May 6–7 in London with JetBrains among the exhibitors. Speakers include Marit van Dijk, Cheuk Ting Ho, and Simon Vergauwen. A documentary on the Spring framework is premiering at the event, with a panel featuring Josh Long and Steve Poole. The conference is one of the largest Java-ecosystem events in Europe and serves as a gathering point for JVM tooling, Spring ecosystem updates, and Kotlin adoption. Talks and workshops span performance engineering, AI integration on the JVM, and developer tooling — making it a useful bellwether for where the Java community is heading through 2026.
