 /**
 20  
  * <p>
 21  
  * The default implementation of the {@code BeanFactory} interface.
 22  
  * </p>
 23  
  * <p>
 24  
  * This class creates beans of arbitrary types using reflection. Each time the
 25  
  * {@code createBean()} method is invoked, a new bean instance is
 26  
  * created. A default bean class is not supported.
 27  
  * </p>
 28  
  * <p>
 29  
  * An instance of this factory class will be set as the default bean factory for
 30  
  * the {@link BeanHelper} class. This means that if not bean
 31  
  * factory is specified in a {@link BeanDeclaration}, this
 32  
  * default instance will be used.
 33  
  * </p>
