            }
            continue;
        }
        // Unknown: let's call handler method
        handleUnknownProperty(jp, ctxt, bean, propName);
    }
    // and when we get this far, let's try finalizing the deal:
    ext.complete(jp, ctxt, bean);
    beanDeserializerAdvice.after(bean, jp, ctxt);
    return bean;
