Java Ecosystem Wiki
This is the wiki for the "Java Ecosystem" working group in the Java Community Process.
Goal. Educate and increase awareness around Java ecosystem third party tools and libraries to increase adoption of modern release processes by third party tool and library maintainers.
This working group was formed following JCP EC discussions:
https://jcp.org/aboutJava/communityprocess/ec-public/materials/2023-04-12/JCP_Java_SE_Update_April_2023.pdf
- Overview
▶️ 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.
