RuntimeException for query methods with fields declaration and Pageable parameters [DATAMONGO-1500]

[spring-projects-issues]

yami.veranes opened DATAMONGO-1500 and commented

When I upgrade from version 1.8.4.RELEASE to 1.9.3.RELEASE, I have some problems with serialization of DBRef and Enum

@Query(fields = "{ 'text' : 0, 'statistics' : 0}")
Page<DocumentManualRevision> findByRevisor(User revisor, Pageable p);

the execution of the previous function (where revisor is a dbref of other collection) return the following exception
