looks like it. another method was injecting the security context, so i
moved it to it own class and now it is working. changing from
@ApplicationScoped to @RequestScoped must have uncovered the problem. i
set everything to requestscoped now because all only produce on request

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.

<matthew.broadh...@nbmlaw.co.uk>:
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

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