Will RestEasy supports Jackson 3? Will we have org.jboss.resteasy:resteasy-jackson3-provider ?

Hi,

I am upgrading a Spring Boot application to Spring Boot 4. By default, Spring Boot 4 should work with Jackson 3 library. It happens that my Spring Boot 4 applications also includes a library which depends on RestEasy, which in turn depends on Jackson 2.

I checked the latest version of RestEasy as of today (18 Jun 2026), which is 7.0.2.Final, and found that it still depends on Jackson 2 libraries https://mvnrepository.com/artifact/org.jboss.resteasy/resteasy-client/7.0.2.Final/dependencies .

There is a artifact ID org.jboss.resteasy:resteasy-jackson2-provider on Maven, which is obviously referencing to Jackson 2. However, I can't find org.jboss.resteasy:resteasy-jackson3-provider as of today.

I would like to ask if a new version of RestEasy which supports Jackson 3 (and get rid of Jackson 2) currently under development? Is there any road map (or schedule) for Jackson 3 support available?

Yes, would be important for the resteasy project - otherwise one will have to search for other jaxrs client implementations sooner or later

Apologies for missing these that got filtered out in my email. There is a new https://github.com/resteasy/resteasy-jackson-provider/ project that supports Jackson 3 and will work with RESTEasy 7.0+.
