Java Ecosystem Wiki
This is the wiki for the "Java Ecosystem" working group in the Java Community Process Executive Committee.
Goal. Educate and increase awareness around Java ecosystem third-party tools and libraries to help maintainers adopt modern Java release processes and baselines.
Formed following JCP EC discussions:

▶️ Meetings (latest first)- 📅 2025 meetings
- 📅 2024 meetings
- 🤝 How to join / present
- 📚 Resources
- ❓ FAQ
- 🧭 Code of Conduct
The working group convenes maintainers, build tool authors, IDE vendors, CI/CD platforms, and library/framework teams to:
- Share migration experiences and pain points (e.g., baselining on recent LTS/STS).
- Coordinate on guidance for JPMS, preview/incubator features, Javadoc, bytecode levels, and CI matrices.
- Amplify patterns that reduce lag between JDK releases and ecosystem readiness.
You can help: propose a topic, share a war story, or bring a concrete “blocker” for live triage.
Tip: Expand each month for agenda, links, and takeaways.
