We found the reported issue upgrading Spring Data MongoDB library from 1.3.5.RELEASE to 1.5.5.RELEASE. The issue is triggered querying a nested generic field qualified with a custom class (not primitive). Following snippet shows the nested field we are trying to query:

public class External{
 private Optional<Internal> field = new Optional<Internal>();

The call to mongoOperations throws a NullPointerException originating from AbstractMappingContext. It is a Spring Data Commons class and we noticed that the issue starts from version 1.7.2.RELEASE of this library, just after commit 02046da

Affects: 1.8.5 (Dijkstra SR5)


Backported to: 1.10.1 (Fowler SR1), 1.9.3 (Evans SR3), 1.8.6 (Dijkstra SR6)

Good catch! getPersistentPropertyPath(…) used the raw type for intermediate path segments which dropped type information and thus caused the exception you saw. We're now using the TypeInformation backing the property and thus correctly resolve nested types.

Merged into all of the currently maintained branches. Note, that Dijkstra is really in string maintenance mode with its next and very last service release scheduled for mid July. We strongly recommend to upgrade to a newer release train
