RESTEasy (version 3.0.16) ClientWebTarget is explicitly using ResteasyUriBuilder and at runtime we are getting our Jersey JerseyUriBuilder.

Issue is reproduced using KeyCloak:

When trying to search a user with the API (usersResource.search) we are getting ClassCastException.

The problem is that KeyCloak resteasy (version 3.0.16) ClientWebTarget is explicitly using ResteasyUriBuilder and at runtime we are getting our Jersey JerseyUriBuilder.
We can't remove the Jersey dependency, rest easy should use the abstract UriBuilder instead of using explicitly ResteasyUriBuilder.

Here is our mvn keycloak dependencies:
