Access KeycloakSecurityContext in tomcat servlet without reflection

KeycloakSecurityContext keycloakSecurityContext = (KeycloakSecurityContext) request.getAttribute(KeycloakSecurityContext.class.getName());

Can get context, but cannot cast to KeycloakSecurityContext, because tomcat adapter and servlet was loaded in different classloaders.

java.lang.ClassCastException: class org.keycloak.adapters.RefreshableKeycloakSecurityContext cannot be cast to class org.keycloak.KeycloakSecurityContext
