Undertow has been split into two projects:

• Undertow
• Undertow EE

The new undertow-ee is the Jakarta Servlet and Jakarta WebSockets implementations only and relies on the core of Undertow.

In WFCORE-7475, Undertow Core will be upgraded to 2.4.0 in WIldFly Core. For WildFly this will be a multi-step process.

1. We need to override the version of io.undertow:undertow-core brought in by WildFly Core
2. We need to introduce the io.undertow.ee:undertow-servlet and io.undertow.ee:undertow-websocket dependencies into WildFly.
3. Once this is merged, we can merge the WFCORE-7475 upgrade.
4. Once that PR is merged into core and there is a release, we can delete the overridden io.undertow:undertow-core dependency.
