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.

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.

Current shortcuts

Site MapBrowse the larger curated index of ecosystem and external reference links. AcronymsQuick one-line explanations for JDK, JVM, JLS, JEP, JSR, JAR, WAR, JSP, and more. CompatibilityCross-version view across Java, runtime, tools, and release families. JDK & ToolsJump into the platform/tooling vertical from the ecosystem landing page.

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.
