Apache Jackrabbit: Board Report September 2023


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.

Project Status:

The project is ongoing with moderate activity.

There are no issues requiring board attention at this time.

Membership Data:

There are currently 58 committers and 58 PMC members in this project. The Committer-to-PMC ratio is 1:1.

Community changes, past quarter:

  • Dominique Pfister resigned on 2023-07-17
  • No new committers. Last addition was Rishabh Daim on 2023-04-06.

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 project team introduced a shaded version of Guava and replaced usage of plain Guava with the shaded version. Only one transitive dependency through an Azure SDK library is left. The plan is to remove this final dependency in the next Jackrabbit Oak release.

On June 29th a vulnerability was reported to the security mailing list. The remote code execution in Jackrabbit RMI was handled with CVE-2023-37895 and releases with a fix published on July 25th.

Community Health:

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