Sim. Mas isso leva a uma coisa feia no seu código…
@Immutable
@Entity
public class Modelo {
@Id @GeneratedValue
private final Integer id;
private final String nome;
private final String descricao;
public Modelo(String nome, String descricao) {
this.id = null; //Esse ja vem null pra nao ficar passando id pro construtor
this.nome = nome;
this.descricao = descricao;
}
//tem q ter esse construtor pra satisfazer o hibernate
Modelo() {
this(null, null);
}
//getters
}
A documentaçao lá sobre essa parte ta bem fraquinha mesmo

Eu fiz um teste utilizando uma Entidade imutável com o Hibernate e VRaptor (com o IOGI: http://www.guj.com.br/posts/list/208491.java#1059421), e ele também funciona com o construtor privado.
Usando o exemplo dessa classe privada ficou assim:
public Modelo(String nome, String descricao) {
this.id = null; //Esse ja vem null pra nao ficar passando id pro construtor
this.nome = nome;
this.descricao = descricao;
}
//tem q ter esse construtor pra satisfazer o hibernate
private Modelo() {
this(null, null);
}
OPA!!!
continuei testando, e deu erro com o contrutor privado quando eu chamo o método:
session.load(Selecao.class, id)
Deu o erro:
