Oracle announces the release of Java 24 as part of its regular 6-month update cycle. Java 24 is a short-term support version, with Java 21 currently being the latest LTS version.
With a whopping 24 new features (counted by the number of JEP specifications), Java 24 boasts the highest number of updates in recent Java history. Some of the key feature groups that have reached stable status include:
– Stream Gatherers enhance the Stream API for data gathering and transformation.
– Class File API becomes the standard API for reading, creating, and converting Java class files.
– Ahead-of-Time Class Loading & Linking improves startup speed by preloading and linking classes before the JVM starts.
Another significant change in Java 24 is the sweeping away of outdated features, such as:
– Removal of Windows 32-bit source code segments after their deprecation in Java 21.
– Deprecation of Linux x86 32-bit platform, leaving it as the last remaining x86 32-bit platform.
– Shutdown of Security Manager, previously deprecated in Java 17.
– Notification of the impending discontinuation of Java Native Interface (JNI).
