In RefreshScope, why should we add the processing logic of getClass() when receiving the ContextRefreshedEvent notification - spring-cloud

Question

In org.springframework.cloud.context.scope.refresh.RefreshScope, the logic for processing the ContextRefreshedEvent notification is as follows:
#Override
public void onApplicationEvent(ContextRefreshedEvent event) {
start(event);
}
public void start(ContextRefreshedEvent event) {
if (event.getApplicationContext() == this.context && this.eager
&& this.registry != null) {
eagerlyInitialize();
}
}
private void eagerlyInitialize() {
for (String name : this.context.getBeanDefinitionNames()) {
BeanDefinition definition = this.registry.getBeanDefinition(name);
if (this.getName().equals(definition.getScope())
&& !definition.isLazyInit()) {
Object bean = this.context.getBean(name);
// question 1
if (bean != null) {
// question 2
bean.getClass();
}
}
}
}
Question 1: If the bean does not exist, an exception will be thrown when the getBean method is executed. Why do we need to judge whether the bean is null?
Question 2: It seems meaningless to execute bean.getClass(), but why do you do it？
I hope someone can answer the above two questions. Thanks.
