Java DB is based on the Apache Derby open source project. Oracle's Java DB developers contribute their work back to the Apache Derby community.
Apache Derby is a community-based project which welcomes contributions such as code, papers, use cases, and improved documentation. If you'd like to get involved, please see the Apache Derby community page.
