Java 25 is now generally available, closing out another six-month release cycle. Java 17 remains the current LTS for most CoffeeSprout environments, and Java 25 joins the line-up as an option for teams ready to move forward.
Highlights from Java 25
- Project Leyden preview: faster startup and warm-up for JVM-based microservices, especially those built with Spring Boot 3 and Quarkus 3.
- Foreign Function & Memory API reaches stability: teams can now call native libraries without JNI overhead.
- Virtual threads improvements: scheduler refinements cut context-switch overhead, making high-concurrency services even smoother.
