BeanCurrentlyInCreationException is thrown when multiple threads simultaneously try to create bean

[marosrojis]

Affects: 6.2.1

It is similar problem what is described in the issue 33972.

After upgrade to Spring boot 3.4.0 (Spring 6.2.0) we sometimes see a BeanCurrentlyInCreationException in our logs after application startup.
I upgraded to Spring boot 3.4.1 (with fix from the issue 33972 but BeanCurrentlyInCreationException still pops up from time to time.

My application is Spring gateway using WebFlux.

Unfortunately I cannot reproduce it in the unit or integration tests.

This was working fine in spring 6.1.15 and is broken in 6.2.0 and 6.2.1.

I enable TRACE log messages from classes org.springframework.beans.factory.support.DefaultListableBeanFactory and org.springframework.context.annotation.ConfigurationClassBeanDefinitionReader.

@marosrojis I've revised this towards on-demand locking for a specific bean when encountering a BeanCurrentlyInCreationException in a non-locked thread. This is available in the latest 6.2.2 snapshot now; please give it an early try if you have the chance (before 6.2.2 becomes generally available on Thursday).

[marosrojis]

@jhoeller I tested my application with 6.2.2-SNAPSHOT.
It works well again, good job :) Thank you for your help.

[jhoeller]

Good to hear! Thanks for the immediate feedback, @marosrojis.

Good to hear! Thanks for the immediate feedback, @marosrojis.

We had quite same issue on several Spring (not spring boot) webapps when migrating from 6.1.x to 6.2.1.
The latest 6.2.2-SNAPSHOT was fixing most of them, but we still facing issue on one of them.

org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'dataSource': Requested bean is currently in creation: Is there an unresolvable circular reference or an asynchronous initialization dependency

Should I create a new issue @jhoeller or simply add you more information (because I'm aware that above log is unhelpful like that) on this thread (starting tomorrow 16jan GMT+1)?

As of 6.2.2, this kind of issue can only happen if another thread concurrently initializes common beans while the main thread tries to initialize all singletons in the preInstantiateSingletons phase. In general, such uncontrolled concurrent startup is not expected in web applications. Other threads are supposed to wait before hitting the context until the ContextLoaderListener has finished its initialization step. Before 6.2, this might implicitly have happened due to waiting for the singleton lock but it really should have been guarded by a custom lock even before.

You'll need to find out which other threads hit the context there and make them wait until the context has been fully initialized. Or at least, make sure that the affected beans (such as 'userExportManager' in your case) are initialized early enough - namely, before those other threads start creating beans that depend on those common beans. The startup order can be enforced through corresponding @DependsOn declarations between those beans, for example from some bean that internally starts a thread (that in turn triggers the creation of other beans) to the common beans that need to be created first.
