	 * The default is {@code true}, allowing for 'inter-bean references' within the

	 * {@code @Bean} methods, e.g. from another configuration class. If this is not needed
	 * since each of this particular configuration's {@code @Bean} methods is
	 * self-contained and designed as a plain factory method for container use, switch
	 * this flag to {@code false} in order to avoid CGLIB subclass processing.
	 * <p>
	 * Turning off bean method interception effectively processes {@code @Bean} methods
	 * individually like when declared on non-{@code @Configuration} classes, a.k.a.
	 * "@Bean Lite Mode" (see {@link Bean @Bean's javadoc}). It is therefore behaviorally
	 * equivalent to removing the {@code @Configuration} stereotype.
