According to the sourcecode of SimpleJpaRepository it should work, because @Nullable says it will accept null:
@Override
public Page<T> findAll(@Nullable Specification<T> spec, Pageable pageable) {
TypedQuery<T> query = getQuery(spec, pageable);
return isUnpaged(pageable) ? new PageImpl<T>(query.getResultList())
: readPage(query, getDomainClass(), pageable, spec);
}
