StableValue and SegmentMapper - Improving Java Performance and Memory Access

Explore a technical conference talk from Devoxx Belgium 2024 that delves into two significant Java enhancements: StableValues and SegmentMapper. Learn how StableValues extends the benefits of the @Stable annotation, previously limited to internal JDK classes, to regular Java applications, enabling improved performance and energy efficiency for fields that change at most once. Discover how SegmentMapper enhances the Foreign Function & Memory API by enabling structured memory mapping to standard Java composites like record classes, expanding beyond basic primitive value access. Presented by Oracle's Java Platform Group Technical Staff member Per-Ake Minborg, gain insights into these upcoming features that aim to make Java more powerful and versatile for developers.
