Hibernate Envers: AuditQuery throws ClasscastException - spring

Question

I have a basic entity called Report, which is annotated with #Audited annotation. Changes to the entity are being stored in the database correctly by envers, where I have a number of revisions for the Report entity ID 1.
The following code is being used by my DAO class to retrieve a a list of all revisions from the audit table:
AuditReader auditReader = AuditReaderFactory.get(sessionFactory.getCurrentSession());
AuditQuery query = auditReader.createQuery().forRevisionsOfEntity(Report.class, true, true);
query.add(AuditEntity.id().eq(1);
List<Object[]> auditList = query.getResultList();
The last line in this code snippet throws the following exception, and I can't seem to figure out why:

Could anybody help explain why that might be the case?
