Why do my Spring Data MongoDB repositories fail to bootstrap after an upgrade to the latest version?

I recently updated a small project to Java 8. This project uses spring-data-mongodb. I upgraded all spring dependency versions to their latest stable version. spring-data-mongodb is running on 1.5.2.RELEASE.

<dependency>
  <groupId>org.springframework.data</groupId>
  <artifactId>spring-data-mongodb</artifactId>
  <version>1.5.2.RELEASE</version>
</dependency>

Whenever I start the service, I get a MappingException for java.lang.Object.

Here's the stacktrace:

15:21:51.177 [main] ERROR o.s.web.servlet.DispatcherServlet - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'pageableIdsRepository': Invocation of init method failed; nested exception is org.springframework.data.mapping.model.MappingException: Could not lookup mapping metadata for domain class java.lang.Object!

    ... 67 common frames omitted

Where is this java.lang.Object coming from and why can't it be mapped correctly?

I debugged the library and it appears that the java.lang.Object class is passed more than once.. perhaps once for Java 8 and once for another version? As you can see, I'm running out of ideas :).

The most surprising thing to me was that by Googling this issue I couldn't find anything relevant.

From the exception it looks like the scanning for Spring Data repositories is picking up an intermediate repository that's not intended to become a real repository instance, but rather contains some generic declaration your other repositories define concrete types for.

This can be solved by annotating the PageableIdsRepositorywith @NoRepositoryBean. The details of that are explained in the corresponding section of the reference documentation.

The reason you see that pop up now is that you've probably been on a version of Spring Data MongoDB before that didn't instantiate repositories eagerly so that as long as nobody actually injected a PageableIdsRepository it would've not been created. We've changed that at some point to eager instantiation this is the default for other Spring beans as well.
