Apache Wicket 9.0.0-M1 released

The Apache Wicket PMC is proud to announce Apache Wicket 9.0.0-M1!

Apache Wicket is an open source Java component oriented web application framework that powers thousands of web applications and web sites for governments, stores, universities, cities, banks, email providers, and more. You can find more about Apache Wicket at https://wicket.apache.org

This release marks the first milestone of the major release of Wicket 9. Since Wicket 9 is still in development, backward api compatibility between milestone release is not guaranteed. We will continue to use semantic versioning when we will made Wicket 9 final and maintain api compatibility between minor versions of Wicket 9.

New and noteworthy

Java 11 support

The new milestone requires Java 11 as minimum version.

JUnit 5 support

Wicket 9 has been migrated from JUnit 4 to 5. Module junit-vintage-engine is provided as test dependency to make old tests work without migrating all the code to JUnit 5.

Test with newer Java versions

Wicket 9 branch is also tested with Java 12 and 13 as part of OpenJDK Quality Outreach project lead by Oracle OpenJDK team. For more informations see the following link:

Rework page and data storage

The internal mechanism used to store page instances has been reworked and refactored to be simpler and easier to use.

Using this release

With Apache Maven update your dependency to (and don’t forget to update any other dependencies on Wicket projects to the same version):

org.apache.wicket wicket-core 9.0.0-M1

Or download and build the distribution yourself, or use our convenience binary package you can find here:

Download: http://wicket.apache.org/start/wicket-9.x.html#manually

Upgrading from earlier versions

If you upgrade from 9.y.z this release is a drop in replacement. If you come from a version prior to 9.0.0, please read our Wicket 9 migration guide found at

Have fun!
