OneToMany join on non PK Composite key - not mapped to a single property

Hibernate ORM
3

Thx @vlad for response.

I change to mappedBy and it works for primary key relation.
But I need join on non primary key column and one from primary key.
I use TENANT_ID and TAX_NUMBER instead of TENANT_ID and ID.

Example with exception:

package org.hibernate.bugs;

import java.io.Serializable;
import java.util.Set;
import javax.persistence.Column;
import javax.persistence.Embeddable;
import javax.persistence.EmbeddedId;
import javax.persistence.Entity;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.FetchType;
import javax.persistence.JoinColumn;
import javax.persistence.JoinColumns;
import javax.persistence.ManyToOne;
import javax.persistence.OneToMany;
import javax.persistence.Persistence;
import javax.persistence.TypedQuery;
import org.hibernate.annotations.Formula;
import org.junit.Before;
import org.junit.Test;

public class NonPkCompositeKey {

  private EntityManagerFactory templatePU;

  @Before
  public void init() {
    templatePU = Persistence.createEntityManagerFactory("templatePU");
  }

  @Test
  public void mappingTest() throws Exception {
    final EntityManager entityManager = templatePU.createEntityManager();
    final TypedQuery<EntityA> query = entityManager
        .createQuery("from NonPkCompositeKey$EntityA a join fetch a.entityBSet", EntityA.class);
    query.getResultList();
  }


  @Entity
  public static class EntityA {

    @EmbeddedId
    private TenantId id;
    @Column(name = "TAX_NUMBER")
    private Long entityB_businessId;
    @OneToMany(mappedBy = "entityA")
    private Set<EntityB> entityBSet;
  }

  @Entity
  public static class EntityB {

    @EmbeddedId
    private TenantId id;
    @Column(name = "TAX_NUMBER")
    private Long entityB_businessId;
    @ManyToOne(fetch = FetchType.LAZY)
    @JoinColumns({
        @JoinColumn(name = "TENANT_ID", referencedColumnName = "TENANT_ID",
            insertable=false, updatable=false),
        @JoinColumn(name = "TAX_NUMBER", referencedColumnName = "TAX_NUMBER",
            insertable=false, updatable=false)
    })
    private EntityA entityA;
  }

  @Embeddable
  public static class TenantId implements Serializable {

    private Long id;
    @Column(name = "TENANT_ID")
    private Long tenantId;
  }
}
