Apache Jackrabbit: Board Report March 2021


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 1.38.0 that was made available on January 28th.

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.

Mid-February the team decided to drop support and deprecate the 1.2 branch of Apache Jackrabbit Oak. Users are encouraged to upgrade to the latest stable 1.38.0 version (

On March 1st a JCRSITE issue was created with spam content. The ticket INFRA-21489 was processed very quickly by the ASF infrastructure team. Thanks! At the same time the Jackrabbit team also noticed Jukka Zitting is set as the project lead for the JCRSITE. Jukka is not active anymore on the project and INFRA-21488 requests a change of the project lead.
