After a Decade, Project Valhalla Finally Ships in JDK 28

Project Valhalla, a ten-year effort to enable Java classes to run with primitive-level efficiency, is finally being integrated into JDK 28 as a preview feature. This development addresses a fundamental architectural limitation in Java where all objects carry memory overhead and require pointer indirection. While this is only the first phase, the successful integration marks a pivotal moment in Java's evolution toward greater performance efficiency.
