Spring could not create EntityManagerFactory after upgrading to Hibernate 5.x

Question

I'm using latest springframework disto v4.2.5.RELEASE and Hibernate v5.0.7.Final when spring loads EntityManagerFactory i'm getting the below exception

Caused by: org.hibernate.HibernateException: Not all named super-types (extends) were found : [com.sample.model.Sample]
at org.hibernate.boot.model.source.internal.hbm.EntityHierarchyBuilder.buildHierarchies(EntityHierarchyBuilder.java:76)

The same code was working with v4.2.5.RELEASE and Hibernate v.4.3.10.

I know Hibernate changed core metadata building in v5.x, is there anything needs to be specified in spring config of JPA/EntityManagerFactory/Hibernate Properties to make it work with Hibernate 5.x?

@Entity
@Table(name = "tbl_sample")
public class Sample extends Auditable {
  private Long id;
  @ManyToOne
  @JoinColumn(name = "relationA", nullable = true)
  private RelationA relationA;
  ... etc
}

@MappedSuperClass
public abstract class Auditable extends Persistable {
   //audit props
}

@MappedSuperClass
public abstract class Persistable {
   //common props
}

I could able to narrow down the issue after enabling trace log, there was one more class which is extending Sample Class and its mapped using hbm.xml like below

<hibernate-mapping package="com.sample.model">  
  <joined-subclass name="BloodSample" table="tbl_blood_sample"
   extends="com.sample.model.Sample">
   <key column="ID" />

  <property name="sampleNo" column="sampleNo"/>
   etc....
 </joined-subclass>

The moment i removed this relation hbm it started working... Still wondering why its happening now which was not in older version of hibernate.

So i guess this issue is nothing to do with spring but something related hibernate. Any insight ?

its custom class like in the pseudo code, which is having auditable fields like createdBy modifiedDate etc — Sreekanth, Mar 10 '16 at 07:54
Looks like one of These classes is not found: `Not all named super-types (extends) were found ` — Jens, Mar 10 '16 at 07:56
@Jens sorry didn get your point, you mean class not found ? but the same code works in Hibernate v 4.3.10 — Sreekanth, Mar 10 '16 at 07:59
https://hibernate.atlassian.net/browse/HHH-10609 probably its a bug in hibernate core matadata builder — Sreekanth, Mar 15 '16 at 05:36

I have a similar your issue. You try to class tag instead joined-subclass tag in hbm.xml file

adding more details would be helpful! – Arun Xavier Mar 15 '16 at 09:38
@nhiendat Does class replaces in favor of joined-subclass ? changing to class work as it would be like joined-subclass ? – Sreekanth Mar 15 '16 at 10:04
Yes, i had replaced class name for joined-subclass. Ex: table="tbl_blood_sample" -> class= "BloodSample" => replace following: – nhiendat May 18 '16 at 02:45
