NullPointerException in RepositoryFactoryBeanSupport.getObject(…) [DATACMNS-1642]

[spring-projects-issues]

Mark Paluch opened DATACMNS-1642 and commented

Trying to bootstrap a repository can lead to a NullPointerException in RepositoryFactoryBeanSupport.getObject(…).

 

What happens:

• RepositoryFactoryBean gets initialized in afterPropertiesSet()
• Initialization requests the type from the MappingContext
• MappingContext publishes an application event
• ApplicationEventMulticaster looks up event listeners from the context
• Bean lookup calls getObject(…) method on the RepositoryFactoryBean that is currently initialized. The repository field was not yet set therefore the call fails with an NPE

 

Stack trace and reproducer are attached

It turns out that the repository factory bean that is under initialization produces a type that is required by an ApplicationEventListener
