We have rest easy dependencies – see below, the problem is that in addition to it we also have Jersey dependency, and at runtime the RuntimeDelegate picks up the Jersey implementation.

Admin client lib requires RestEasy. If you're using WildFly or JBoss EAP you can create a module for the admin client library and add RestEasy dependencies to that.

Hi,

 

We are using KeyCloak 1.9.3, 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.

Any idea how to overcome it ? assuming we can't remove the Jersey dependency.

 

Exception stack trace:

java.lang.ClassCastException: org.glassfish.jersey.uri.internal.JerseyUriBuilder cannot be cast to org.jboss.resteasy.specimpl.ResteasyUriBuilder
