@csplrji, this was fixed in 5.0.10, 5.1.1, and 5.2.0. If you are still having problems with any of those versions, then please create a new jira issue.

This issue comes in 5.0.2 as well

Fixed in master, 5.1, and 5.0 branches.

I've incorporated the tests from the pull request, added more tests and a fix into a new commit pushed to my fork: https://github.com/gbadner/hibernate-core/commits/HHH-10476-master

I've create a pull request with a FailureExpected unit test that reproduces this issue: https://github.com/hibernate/hibernate-orm/pull/1275
I am getting an exception: "Caused by: javax.persistence.EntityExistsException: A different object with the same identifier value was already associated with the session: [com.efl.mobility.puma.dao.model.content.ProductDL#ukdipabk]" when I get (find method) an entity by its compound key. This exception only be thrown when one entity, at least, of compound key is previously loaded in session.
Simple Entity 1:
CustomerDL.java
@Entity(name="Customer") public class CustomerDL implements Serializable { private long customerId; ... }Simple entity 2:
ProductDL.java
@Entity @Table(name="CNT_PRODUCT") public class ProductDL extends Auditory implements Serializable { private String productCod; ... }Entity with compound key:
SubscriptionDL.java
public class SubscriptionDL implements Serializable { private SubscriptionIdDL subscriptionId; @EmbeddedId public SubscriptionIdDL getSubscriptionId() { return subscriptionId; } public void setSubscriptionId(SubscriptionIdDL subscriptionId) { this.subscriptionId = subscriptionId; } }Embedded id:
SubscriptionIdDL.java
public class SubscriptionIdDL implements Serializable { private CustomerDL customer; private ProductDL product; @OneToOne @JoinColumn(name="CUS_ID", referencedColumnName="CUS_ID", nullable=false) public CustomerDL getCustomer() { return customer; } public void setCustomer(CustomerDL customer) { this.customer = customer; } @ManyToOne @JoinColumn(name="CNT_PRODUCT_COD", referencedColumnName="CNT_PRODUCT_COD", nullable=false) public ProductDL getProduct() { return product; } public void setProduct(ProductDL product) { this.product = product; } }Steps to reproduce the exception:
1) Load with session find (by id) method an entity of type CustomerDL.
2) Create an entity (also fails if this entity is loaded from session) of type ProductDL and fill its id.
3) Create compound key (SubscriptionIdDL) with (1) and (2) entities.
4) Load with session find (by id) method an entity of type SubscriptionDL using (3) generated Key.
Example (using a service layer):
test.java
ProductSL productSL=productService.get("ukdipabk"); CustomerSL customerSL2=new CustomerSL(); customerSL2.setCustomerId(2L); subscriptionIdSL=new SubscriptionIdSL(); subscriptionIdSL.setProduct(productSL); subscriptionIdSL.setCustomer(customerSL2); subscriptionService.get(subscriptionIdSL); //launch "already associated exception"emphasis NOTE: all code executed in one transaction so one hibernate session.
In Hibernate 4 version using exactly same code this work fine.
