[hibernate-dev] Why do Services need to be Serializable?

[Sanne Grinovero]

I just found this comment on org.hibernate.service.Service:

/**
 * Marker interface for services.
 * <p/>
 * NOTE : All services must be {@link Serializable}!
 *
 * @author Steve Ebersole
 */
public interface Service extends Serializable {


What kind of bad things will happen to us if violating this recommendation?

In OGM we have for example connection pools managed in a Service, we
can hardly serialize that.
