[keycloak-user] Admin Client

[Marko Strukelj]

That error can happen when jboss modules dependencies are misconfigured.
RealmRepresentation class is part of keycloak-core module, and should only
be available through that module. What that means is that you should
declare a dependency on keycloak-core module in your module (whatever that
is - maybe jboss-deployment-structure.xml for your .war), but make sure not
to reexport the dependency content.

The following for example would be a wrong way to declare a module
dependency:

<module name="org.keycloak.keycloak-core" export="true"/>
