      • assignLazyLoadProxies

        public static void assignLazyLoadProxies​(StateManagerImpl sm)
        Create a container instance that will delegate back to the state manager to emulate lazy loading. This is used by PC subclasses for unenhanced types that could not be redefined, and thus do not have field-interception capabilities. Do this for all collection and map field types, even if they are in the dfg, in case the fetch groups are reset at runtime.
