/**
 * Exception thrown if a FactoryBean is not fully initialized, for example
 * because it is involved in a circular reference. Usually indicated by
 * the <code>getObject</code> method returning null.
 *
 * <p>A circular reference with a FactoryBean cannot be solved by eagerly
 * caching singleton instances like with normal beans. The reason is that
 * <i>every</i> FactoryBean needs to be fully initialized before it can
 * return the created bean, while only <i>specific</i> normal beans need
 * to be initialized - that is, if a collaborating bean actually invokes
 * them on initialization instead of just storing the reference.
