OpenJDK Libraries Frameworks Toolchains References

The Java ecosystem is bigger than the language or the runtime.

This page is the shared landing page for the wider Java world: standards, OpenJDK projects, frameworks, libraries, packaging, build tools, diagnostics, and the practical reference material teams use every day. The ecosystem also has to plan around the future LTS line because framework support and tool adoption tend to follow it.

What belongs here

OpenJDK projects such as Loom, Panama, Valhalla, and Leyden.
Framework layers like Spring, Jakarta EE, and related enterprise tooling.
Build and packaging workflows such as Maven, Gradle, JARs, modules, and containers.
Reference hubs like the Java specs, JEP index, compatibility tables, and glossary pages.

Future LTS impact on the ecosystem

Future LTS anchors matter far beyond the JDK itself. Spring, Jakarta EE implementations, build plugins, IDE support, testing stacks, container baselines, and vendor support matrices usually realign around the visible LTS line.

Next visible anchors: Java 29 (planned), Java 33 (projected), Java 37 (projected), Java 41 (projected).

Planned expansion

This is a working landing page for the ecosystem vertical. The next natural additions are framework families, build systems, packaging formats, community processes, major IDE/tooling paths, and a cleaner bridge to OpenJDK projects.
