Stefan Fleiter opened SPR-4307 and commented

Neither spring's reference documentation nor the Javadoc mention the context thread-safety and visibility guarantees.

What can happen when multiple threads query for a bean during its' creation (singleton and prototype)?
Is it guaranteed that all threads see changes made by constructors and setters?
Does FactoryBean#getObject() has to be implemented thread-safe?

After a short analysis of AbstractBeanFactory all these aspects seem to be handled by the spring context.

Please document this.
The most important place is the reference documentation:
http://static.springframework.org/spring/docs/2.5.x/reference/beans.html
The Javadoc for all ApplicationContext- and BeanFactory-Classes should also state this.

Thanks a lot in advance.
