Apache Jackrabbit: Board Report September 2022


The Apache Jackrabbit™ content repository is a fully conforming implementation of the Content Repository for Java™ Technology API (JCR, specified in JSR 170 and 283). The Jackrabbit content repository is stable, largely feature complete and actively being maintained.

Jackrabbit Oak is an effort to implement a scalable and performant hierarchical content repository as a modern successor to the Apache Jackrabbit content repository. It is targeted for use as the foundation of modern world-class websites and other demanding content applications. In contrast to its predecessor, Oak does not implement all optional features from the JSR specifications, and it is not a reference implementation.


There are no issues requiring board attention at this time.

Project Activity:

Apache Jackrabbit Oak receives most attention nowadays. All maintenance branches and the main development branch are continuously seeing moderate to high activity.

Apache Jackrabbit itself is mostly in maintenance mode with most of the work going into bug fixing and tooling. New features are mainly driven by dependencies from Jackrabbit Oak.

The team decided to introduce a GitHub action that adds a label to open pull requests for Jackrabbit Oak that are older than two years. The intention is to reduce the number of open or abandoned pull requests and notify contributors to follow up on their change request. Stale pull requests without further activity are then closed automatically after 30 days.

Community Health:

The project is healthy with a continuous stream of traffic mostly on the JIRA issues and GitHub pull requests reflecting the activity of the respective component.

Commit activity is moderate, mirroring the activity on the JIRA issues and the desire of the individual contributors to bring features and improvements in for the next Jackrabbit Oak release.
