You’re using a mix of versions of RESTEasy, which you should not be doing. You're also including two different versions of the Jakarta REST API which are not compatible with each other.
For Keycloak 26, RESTEasy is longer used and Quarkst REST, formally RESTEasy Reactive, should be used. You'll need to migrate to using the new REST Client implementation.
As a simple breakdown for RESTEasy itself. RESTEasy 4.7 targets Jakarta REST 2.1. RESTEasy 6.2 targets Jakarta REST 3.1 and RESTEasy 7.0 targets Jakarta REST 4.0.
