Apache Jackrabbit: Board Report March 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.


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 1.24.0 that was made available on January 28th.

The upcoming Jackrabbit Oak 1.26.0 release will finally remove usage of, a deprecated interface that will be removed in Java 14.

The security issue was initially discovered by Andrew Khoury and Russ Wright of Adobe. Details on the security issue are available in and

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.
