[keycloak-user] updating owner of a resource

Hi, I was trying to update the owner of an existing resource with resource.setOwner(newOwnerId); getAuthzClient().protection().resource().update(resource); There is no Exception, but it seems that resource still keeps the previous owner... is there a different way to achieve this? Is it possible at all? thanks gianni PS: the server is keycloak 4.8.3Final
