But in this case we check that `QueryEntityMerger#merge` even though we do not explicitely set key type for the first entity. So when we start merging the key type of the first entity is null. Thus, we check that the `mergeKeyType()` helper in `QueryEntityMerger` works correctly by using `findKeyType()` and not `getKeyType()`, which would return null and do incorrect merging null + String → String. So the collision here happens not because key type was set implicitly for the first entity, but because two entities have the same valye type (`Person.class`). -- This is an automated message from the Apache Git Service.
