JDK 25: The new features in Java 25

Java Development Kit (JDK) 25, scheduled for release in September 2025, is set to introduce several significant enhancements. Here's an overview of the notable features: 1. Stable Values API (Preview): This feature introduces stable values—objects holding immutable data treated as constants by the Java Virtual Machine (JVM). By allowing greater flexibility in initialization timing compared to final fields, stable values aim to improve application startup times. They enable performance optimizations akin to constant-folding, previously exclusive to JDK code, and ensure thread-safe, single-time initialization. This decouples the creation of stable values from their initialization without significant performance penalties. 2. Removal of 32-bit x86 Port: JDK 25 plans to eliminate both the source code and build support for the 32-bit x86 port, which was deprecated in JDK 24. Maintaining this port has become less beneficial, especially with the challenges in keeping it updated wit...
