Java 25 is here. Oracle released JDK 25 (LTS) on September 16, 2025, with quarterly updates planned through September 2028. The release includes new language and runtime features, along with improvements aimed at AI workloads. Picking a vendor that supports LTS roadmaps keeps your stack secure and maintainable.

Java usage stays strong. JetBrains’ 2024 ecosystem survey shows Java holding steady over the last 7 years, with roughly half of developers using it in that period. That stability is one reason large firms keep choosing Java for core systems.

Upgrades are speeding up. New Relic reported 1.4% of apps moved to Java 21 within six months of its release, a faster pace than Java 17 early adoption. Teams with good pipelines can now adopt new JDKs sooner without risking uptime.
