Comment From: wilkinsona

I believe the problem will occur when refresh fails in any application with an ImportAware bean. The import registry is registered as a singleton (SingletonBeanRegistry.registerSingleton(String, Object)). When refresh fails, AbstractApplicationContext catches the BeansException and calls destroyBeans. This ultimately removes the import registry from the bean factory. Subsequently, SpringApplication catches the failure and closes the context. This leads to the publishing of an AvailabilityChangeEvent and causes the context to retrieve all application listeners. This results in bean creation and post-processing at which point ConfigurationClassPostProcessor$ImportAwareBeanPostProcessor is called. It attempts to retrieve the import registry singleton but it fails as it's no longer registered. In short things have got into a state where the ImportAwareBeanPostProcessor is registered but the import registry upon which it depends is not.

When the refresh fails, the active flag is set to false. This should prevent the closing of the context from having any effect, however we're publishing the event before the flag is checked in the super call:

https://github.com/spring-projects/spring-boot/blob/840b029f10daf6e62cff84e0f1bf2b2a4a276060/spring-boot-project/spring-boot/src/main/java/org/springframework/boot/web/reactive/context/ReactiveWebServerApplicationContext.java#L137-L141

I think we should be able to fix the problem by only publishing the AvailabilityChangeEvent when the context is active.

Comment From: filiphr

Just FYI, since I posted initially the problem we had in https://github.com/spring-projects/spring-boot/issues/21507#issuecomment-633933653, we are not using the Reactive stack, but the Servlet one. Although I assume the problem is similar between both of the stacks.

Comment From: wilkinsona

@filiphr Thanks for double-checking. Yeah, the servlet web server application context has the same problem.

Comment From: gjgarryuan

I just upgraded spring boot to 2.3.0-RELEASE and encountered this issue.

Is there a workaround for this? Or do I need to stay with 2.2.x until 2.3.1 is released?

Comment From: wilkinsona

There's no workaround, but the problem is somewhat benign. It will only occur as a result of an earlier failure to refresh the application context. If you address the cause of the refresh failure, the problem fixed by this issue will not occur.

Comment From: gjgarryuan

Ah thanks I figured it out.

The Bean Validation API is on the classpath but no implementation could be found

It seems like org.springframework.boot:spring-boot-starter-webflux:jar:2.3.0.RELEASE no longer bundles with org.springframework.boot:spring-boot-starter-validation:jar:2.3.0.RELEASE.

^ Sorry if this is not strictly related.

Comment From: wilkinsona

That's right. Please see this section of the release notes for details.

Comment From: chandlerb

I am also experiencing the same issue regarding NoSuchBeanDefinitionException for org.springframework.context.annotation.ConfigurationClassPostProcessor.importRegistry after the upgraded spring boot to 2.3.0-RELEASE is there a fix for this

Comment From: philwebb

@chandlerb Have you follow the release notes section referenced above?

Hi @chandlerb what s the solution?

Comment From: wxbty

I'm wondering, under what circumstances would this line of code be triggered. If there is no scene, why not just delete it.

        if (this.isActive()) {
            AvailabilityChangeEvent.publish(this, ReadinessState.REFUSING_TRAFFIC);
        }
