JPA Criteria Query with predicate that compares a field annotated @Convert gets a ORA-00932 upon execution

Question

I'm developing a Java EE 7 application (persistence provider is Hibernate 4.3.5, DB is Oracle 11g) in which I'm using a entity class with a Long field that represents the millis of a date. It's been done that way to avoid the problems of using DBs' date datatypes (e.g. timezone handling). Here's the relevant entity class code:

import java.util.Date;

@Table
@Entity
public class Transference implements Serializable {

    private static final long serialVersionUID = 1L;

    // ... elided fields

    private Date dateTime;

    // ... elided setters and getters

    @Column(name = "datetime")
    @Convert(converter = DateConverter.class)
    @NotNull
    public Date getDateTime() {
        return dateTime;
    }

}

Attribute in the metamodel class:

public static volatile SingularAttribute<Transference, Date> dateTime;

Here's the straightforward JPA 2.1 converter:

import java.util.Date;

@Converter
public class DateConverter implements AttributeConverter<Date, Long> {

    @Override
    public Long convertToDatabaseColumn(Date attribute) {
        return (attribute == null)? null : attribute.getTime();
    }

    @Override
    public Date convertToEntityAttribute(Long dbData) {
        return dbData == null? null : new Date(dbData);
    }

}

Table definition:

CREATE TABLE transference (
-- fields ...
datetime NUMBER(20) NOT NULL,
-- constraints...
);

Persisting and reading the field value works like a charm. The problem comes when I try to use a predicate in a CriteriaQuery that compares the field with a value:

private List<Transference> queryResultList() {
    CriteriaBuilder cb = this.entityManager.getCriteriaBuilder();
    CriteriaQuery<Transference> cq = cb.createQuery(Transference.class);
    Root<Transference> root = cq.from(Transference.class);
    List<Predicate> predicates = new ArrayList<>();

    // Predicates with other fields...

    if (this.dateTo != null) {
        Path<Date> pathDateTo = root.get(Transference_.dateTime);
        Predicate predDateTo = cb.greaterThanOrEqualTo(pathDateTo, this.dateTo);
        predicates.add(predDateTo);
    }

    Order orderBy = cb.desc(root.get(Transference_.dateTime));
    Predicate[] predicatesArray = {};

    cq.select(root).where(predicates.toArray(predicatesArray)).orderBy(orderBy);

    TypedQuery<Transference> tq = this.getEntityManager().createQuery(cq);
    return tq.getResultList();  // <- A exception is thrown here, when predDateTo is used in the query.

}

This is the exception I am getting:

java.sql.SQLSyntaxErrorException: ORA-00932: inconsistent datatypes: expected NUMBER got TIMESTAMP

What is the right way to use such a field in a criteria query predicate? The converter only works for reading/persisting. I've been looking for a way and been unable to, even in the JPA 2.1 specification (which is very large, by the way). What am I missing here? Thanks for your attention.

Thanks for your kind answers. I couldn't figure out how to use the field, but I came up with this (not so pretty) workaround:

private Date dateTime; // Original field
private Long dateTimeMillis;

@Column(name = "datetime")
@NotNull
@Convert(converter = DateConverter.class)
public Date getDateTime() {
    return dateTime;
}

// Another mapping for the datetime column, will use this for criteria queries:
@Column(name = "datetime", updatable = false, insertable = false)
public Long getDateTimeMillis() {
    return dateTimeMillis;
}

Predicate:

Path<Long> pathDateTo = root.get(Transference_.dateTimeMillis);
Predicate predDateTo = cb.lessThanOrEqualTo(pathDateTo, this.dateTo.getTime());
predicates.add(predDateTo);

Then it works as expected.
