GOTO Conferences

A panel discussion featuring Spring founder Rod Johnson, Spring contributor Arjen Poutsma, and moderator Trisha Gee covering the evolution of the Spring framework, its future direction, and the broader Java ecosystem. Key topics include the declining relevance of reactive programming with the rise of virtual threads, Spring Modulith and the microservices pendulum swinging back, Java/Kotlin tradeoffs, collaboration between the Spring and Oracle/GraalVM teams on ahead-of-time compilation, and the introduction of Embabel — Rod Johnson's new JVM agent framework built on top of Spring AI for multi-step agentic flows. The panel also addresses enterprise AI adoption challenges including data privacy, local model usage, and the need for Java developers to build foundational GenAI knowledge comparable to what Python developers already have.
