org.springframework.beans.factory.FactoryBeanNotInitializedException
Exception to be thrown from a FactoryBean's getObject() method if the bean is not fully initialized yet, for example because it is involved in a circular reference.
Note: A circular reference with a FactoryBean cannot be solved by eagerly caching singleton instances like with normal beans. The reason is that every FactoryBean needs to be fully initialized before it can return the created bean, while only specific normal beans need to be initialized - that is, if a collaborating bean actually invokes them on initialization instead of just storing the reference. @author Juergen Hoeller @since 30.10.2003 @see FactoryBean#getObject()

    @Override
    public Object getObject() throws Exception {


        // make sure the factory is fully initialized
        if (!initialized) {
            throw new FactoryBeanNotInitializedException();
        }


        // create the invocation handler that switches between implementations
        Feature namedFeature = new NamedFeature(feature);
        FeatureProxyInvocationHandler proxy = new FeatureProxyInvocationHandler(namedFeature, active, inactive);
