Apache Jackrabbit: Board Report December 2020 (draft)

Description:

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.

Issues:

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 1.36.0 that was made available on November 17th.

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.

In October the team noticed security vulnerabilities with Apache Solr versions in use by Apache Jackrabbit Oak (CVE-2020-13941, CVE-2019-17558, CVE-2019-2386). The updated Solr versions with the fixes required a change of the Java version supported by the Jackrabbit Oak maintenance releases. So far Jackrabbit Oak 1.4.x and 1.6.x releases were able to run on Java 7 or newer. With the upgrade of Solr, the minimum version had to be lifted to Java 8 (https://s.apache.org/t40d0).

Beginning of December the team decided to drop support and deprecate the 2.18 branch of Apache Jackrabbit. Users are encouraged to upgrade to the latest stable 2.20.x version (https://s.apache.org/llfe1).

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 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.
