 Post subject: Clob is not cacheable (ignoring @Type)

Using Seam framework (On JBoss AS 4.2.2.GA, Seam 2.0.1.GA) with Hibernate. I would like to use second level cache with Hibernate, but I cannot make it work, as it complains that Clob is not cacheable.
Cannot understand why @Type is ignored and ClobType is used for dissassembling, not my XmlClobType.

Decorating Message class or the property with @Cache(usage = CacheConcurrencyStrategy.NONE) didn't help. I couldn't find where else I could disable caching of entity.

Hibernate version:
    Hibernate EntityManager 3.2.1.GA
    Hibernate Annotations 3.2.1.GA
    Hibernate 3.2.4.sp1


Mapping documents:
persistence.xml

Entity
Code:
@Entity

public class Message implements Serializable

    private Long id;
    private String xml;

    @Id
    @Column(name = "MSG_ID")
    public Long getId()
    {
        return id;
    }

    public void setId(Long id)
    {
        this.id = id;
    }

    @Lob
    @Column(name = "MSG_XML", nullable = false)
    @Type(type = "org.package.XmlClobType")
    public String getXml()
    {
        return xml;
    }

    public void setXml(String xml)
    {
        this.xml = xml;
    }
}


XmlClobType
Code:
public class XmlClobType extends StringClobType
{
    private static final long serialVersionUID = 1L;

    @Override
    public Object assemble(Serializable cached, Object owner) throws HibernateException
    {
        return super.assemble(cached, owner);
    }

    @Override
    public Serializable disassemble(Object value) throws HibernateException
    {
        return super.disassemble(value);
    } 
}

My mistake, I had two entities with clobs though I dealt with only one.

Changing return type to String (instead of Clob) in all entities, fixes caching
