Modification in AbstractAutowireCapableBeanFactory to prevent stackoverflow errors causes context not to load. [SPR-15125]

Jeff Maxwell opened SPR-15125 and commented

Modification in AbstractAutowireCapableBeanFactory to prevent StackOverflowErrors causes context not to load with org.springframework.beans.factory.NoSuchBeanDefinitionException.

This commit causes our code to throw the exception below.

Earlier versions of AbstractAutowireCapableBeanFactory work fine.

Note that the reference.service.instrumentEhcache bean is created via a subclass of org.springframework.cache.ehcache.EhCacheFactoryBean

The context being loaded is rather complex, I have not yet been able to create a minimal test example.

#19119 was a rather important fix since prior to this change we completely bypassed getSingletonFactoryBeanForTypeCheck's currently-in-creation checks, leading to full initialization of the FactoryBean instance for type checking even in circular reference scenarios... with a stack overflow potential even if the type wouldn't match anyway.

So in your case, we seem to back out of checking your FactoryBean's type because we detect a currently-in-creation scenario. You could try to debug this with a breakpoint in getSingletonFactoryBeanForTypeCheck, stepping through the currently-in-creation conditions there.

Are you possibly declaring this FactoryBean on a configuration class, trying to wire its result into the configuration class itself? In such a scenario, please note that the only clean way out is declaring such an @Bean method as static, allowing its instance to be created without relying on a fully initialized configuration class instance around.

Juergen Hoeller commented

Or are you possibly trying to inject a FactoryBean's object outcome into that very same FactoryBean itself?

In any case, please show some configuration snippets for a clearer indication. There is something special about your setup that we do not have a unit test for.

[spring-projects-issues]

Juergen Hoeller commented

I've added a lenient fallback to an early singleton reference of the currently created FactoryBean. Even if this is not recommended, with 4.3's self injection capabilities, it should arguably work.

This will make into tomorrow's 4.3.6.BUILD-SNAPSHOT. If your scenario still isn't working then, please reopen this issue.

Not that I am aware.

It does not appear to do this.

I have struggled to create a minimal unit test of this issue as the configuration/code base is rather labyrinthine.

I will pull and retest.

Unfortunately, there was still some stack overflow potential left, so I haven't committed any change yet. Self references to a FactoryBean - which is what I tested against there out of my wild guess - are inherently dangerous, it seems :-( I'll mark this issues as reopened.

The declarations of your EhCacheFactoryBean subclass and the point where you inject it would help me a lot. Otherwise the only way forward is debugging on your end.

[spring-projects-issues]

Jeff Maxwell commented

We believe that we have narrowed the issue a bit.
There are a couple of cache loaders, including our loader for reference.service.instrumentEhcache, that depend on other caches.
If we remove these dependencies from the reference.service.instrumentEhcache cache loader we do not see the issue.

Does this help?

Juergen Hoeller commented

I've added additional detection of statically declared FactoryBean types in bean class hierarchies as well as static factory methods. So instead of trying to create the full bean instance (which leads to a potential stack overflow), we're now falling back to static introspection if we can't create an early FactoryBean instance. This works fine for our unit tests and should work fine for a standard FactorBean variant like EhCacheFactoryBean as well, as long as the implementation hierarchy declares the FactoryBean's object type in some implements or extends clause.

I'll ping you once this is available in a 4.3.6.BUILD-SNAPSHOT. Would be great if you could give it an early try then...

This is available in the latest 4.3.6.BUILD-SNAPSHOT now. Please give it a try if you have the chance...

(See http://projects.spring.io/spring-framework/ for how to obtain a snapshot from our snapshot repository.)

It works.
Thanks for all your effort.
