Apache Jackrabbit: Board Report June 2020


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 web sites 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.

We continue making regular feature releases of Jackrabbit Oak. The most recent release was Jackrabbit Oak 1.30.0 that was made available on May 27th.

A vulnerability report was sent to the security list on June 4th. The Jackrabbit team is discussing the report and will likely reject it (

The Apache Jackrabbit FileVault component successfully moved from SVN to GIT (INFRA-20285).

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.

On March 26th the team retired the Apache Jackrabbit 2.8 branch. Users of Apache Jackrabbit are encouraged to upgrade to 2.20 for Java 8, 2.14 for Java 7 or 2.12 for Java 6.

On March 31st the team retired the Apache Jackrabbit Oak 1.0 branch. Users of Apache Jackrabbit Oak are encouraged to upgrade to 1.26.0 for Java 8, 1.6.20 for Java 7 or 1.2.31 for Java 6.

On April 6th the team retired the Apache Jackrabbit Oak 1.10 branch. Users of Apache Jackrabbit Oak are encouraged to upgrade to the latest release of the newest maintenance branch (1.22.3).

Community Health:

The project is healthy with a continuous stream of traffic on all mailing lists reflecting the activity of the respective component.

There is a wide range of topics being discussed on the dev and user lists as well as on the various JIRA issues.

Commit activity is moderate to high 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.

The report about a potential vulnerability to the security mailing list revealed that only a small group of mostly passive PMC members are subscribed to the security list. The PMC members were asked to subscribe to the security list in order to add active members to the list.

In the last 3 months the project added two new committers and PMC members.

Martijn Hendriks contacted the PMC and expressed his desire to resign. His resignation from the PMC and committer base became effective on June 5th after his confirmation that he also wants to be removed as a committer.
