StableValue and SegmentMapper: Enhancing Java Performance and Memory Access

Explore two cutting-edge features in Java development: StableValues and SegmentMapper in this 46-minute Devoxx conference talk. Gain insight into the internal JDK class annotation @Stable, which marks fields that change at most once, offering crucial performance and efficiency benefits. Learn how StableValue extends these advantages to regular Java and third-party library developers. Discover how SegmentMapper enhances the Foreign Function & Memory API introduced in Java 22, allowing structured memory to be mapped to standard Java composites like record classes. Uncover the potential of these features to significantly improve Java application performance, energy efficiency, and flexibility.
