Hi
it looks accurate, a normal scoped instance - request scoped - proxies
a not null instance so you can't return null. Using a @RequestScoped
producer class (the enclosing one) and @Dependent producer can work
too if you inject this context in request scoped instances only.

if @Produces can produce null e.g.
@Produces
@Default
@RequestScoped
public KeycloakSecurityContext keycloakSecurityContext() {
if (httpServletRequest.getUserPrincipal() instanceof KeycloakPrincipal)
{
KeycloakPrincipal<KeycloakSecurityContext> keycloakPrincipal =
(KeycloakPrincipal<KeycloakSecurityContext>)
httpServletRequest.getUserPrincipal();
return keycloakPrincipal.getKeycloakSecurityContext();
}
return null;
}
then i get
Caused by:
javax.enterprise.inject.IllegalProductException - WebBeans producer :
keycloakSecurityContext return type in the component implementation class :
uk.me.kissy.external.producers.SecurityProducer scope type must be
@Dependent to create null instance

I can't add @Dependent to the KeycloakSecurityContext class but if I add it
to keycloakSecurityContext() i get

deployment failed
