[keycloak-user] @Inject KeycloakPrincipal in EJB container

Dear community, as the subject says, how can the org.keycloak.KeycloakPrincipal be @Inject-ed in say a @Stateless bean? I tried injecting a java.security.Principal but I couldn't get a KeycloakPrincipal out of it. I also tried creating a CDI @Producer (annotated with @RequestScoped) producing the KeycloakPrincipal but that didn't work either because KeycloakPrincipal can't be proxied. (That's mostly for convenience since @Resource SessionContext ctx and then ctx.getCallerPrincipal() answers the KeycloakPrincipal but I wouldn't want to do that explicitly in every business method) This is on 17.0.1 Wildfly with the Elytron Keycloak adapter. Cheers, Vagelis
