Affects Hibernate ORM 6.2, probably also 6.1 and 6.0, but definitely not 5.6.
ThisWith bytecode enhancement enabled, this model:
{noformat} @Entity(name = "entitya")
public static class EntityA {
@Id
private Integer id;
@Embedded
private EmbeddedValue embedded = new EmbeddedValue();
public EntityA() {
}
private EntityA(Integer id) {
this.id = id;
}
public Integer getId() {
return id;
}
public EmbeddedValue getEmbedded() {
return embedded;
}
public void setEmbedded(EmbeddedValue embedded) {
this.embedded = embedded;
}
}
@Embeddable
public static class EmbeddedValue implements Serializable {
@OneToOne(mappedBy = "entityA", fetch = FetchType.LAZY)
private EntityB entityB;
public EmbeddedValue() {
}
public EntityB getEntityB() {
return entityB;
}
public void setEntityB(
EntityB entityB) {
this.entityB = entityB;
}
}
@Entity(name = "entityb")
public static class EntityB {
@Id
private Integer id;
@OneToOne
private EntityA entityA;
public EntityB() {
}
private EntityB(Integer id) {
this.id = id;
}
public Integer getId() {
return id;
}
public EntityA getEntityA() {
return entityA;
}
public void setEntityA(EntityA entityA) {
this.entityA = entityA;
}
}{noformat}
Leads to this stacktrace upon loading EntityA:
