/**
 * Load a Spring ApplicationContext from the supplied {@link MergedContextConfiguration}.
 *
 * <p>Implementation details:
 *
 * <ul>
 * <li>Calls {@link #validateMergedContextConfiguration(MergedContextConfiguration)}
 * to allow subclasses to validate the supplied configuration before proceeding.</li>
 * <li>Creates a {@link GenericApplicationContext} instance.</li>
 * <li>If the supplied {@code MergedContextConfiguration} references a
 * {@linkplain MergedContextConfiguration#getParent() parent configuration},
 * the corresponding {@link MergedContextConfiguration#getParentApplicationContext()
 * ApplicationContext} will be retrieved and
 * {@linkplain GenericApplicationContext#setParent(ApplicationContext) set as the parent}
 * for the context created by this method.</li>
 * <li>Calls {@link #prepareContext(GenericApplicationContext)} for backwards
 * compatibility with the {@link org.springframework.test.context.ContextLoader
 * ContextLoader} SPI.</li>
 * <li>Calls {@link #prepareContext(ConfigurableApplicationContext, MergedContextConfiguration)}
 * to allow for customizing the context before bean definitions are loaded.</li>
 * <li>Calls {@link #customizeBeanFactory(DefaultListableBeanFactory)} to allow for customizing the
 * context's {@code DefaultListableBeanFactory}.</li>
 * <li>Delegates to {@link #loadBeanDefinitions(GenericApplicationContext, MergedContextConfiguration)}
 * to populate the context from the locations or classes in the supplied
 * {@code MergedContextConfiguration}.</li>
 * <li>Delegates to {@link AnnotationConfigUtils} for
 * {@link AnnotationConfigUtils#registerAnnotationConfigProcessors registering}
 * annotation configuration processors.</li>
 * <li>Calls {@link #customizeContext(GenericApplicationContext)} to allow for customizing the context
 * before it is refreshed.</li>
 * <li>{@link ConfigurableApplicationContext#refresh Refreshes} the
 * context and registers a JVM shutdown hook for it.</li>
 * </ul>
