This looks pretty much like a bi-directional mapping issue I can reproduce the issue with the following JPA code: long userId = 1;
Payment payment = new Payment();
var invoice = new Invoice();
invoice.setId(1L);
payment.setInvoice(invoice);
AppUser appUser = new AppUser();
appUser.setId(userId);
payment.setCreatedFrom(appUser);
entityManager.persist(payment);
Invoice invoiceLoaded = (Invoice) entityManager.createQuery("SELECT i FROM Invoice i WHERE i.id = ?1")
.setParameter(1, invoice.getId()).getSingleResult();
jakarta.persistence.EntityGraph<StudentFeesToInvoice> entityGraph = entityManager
.createEntityGraph(StudentFeesToInvoice.class);
entityGraph.addSubgraph("invoice")
.addSubgraph("payments")
.addAttributeNodes("createdFrom");
// failure happens here
entityManager.createQuery("SELECT s FROM StudentFeesToInvoice s WHERE id = ?1")
.setHint("jakarta.persistence.fetchgraph", entityGraph)
.setParameter(1, invoiceLoaded.getId()).getResultList();I don't think that Hibernate can do much especially when being told to use eager fetching instead of lazy-loading proxies. In any case, please file a bug report with the Hibernate issue tracker as the |

Summary:
I originally posted this as a Spring Boot issue, but since this is JPA/Hibernate related, maybe it belongs here.
After upgrading to Spring Boot 3.4.0 (Hibernate 6.6.2-Final), there is a Hibernate related error when a transactional method, after saving a row, tries to retrieve some data from a repository method using
EntityGraph. This worked in Spring Boot 3.3.5 (Hibernate 6.5.3-Final). As it is mentioned in the original issue, this has to do with using non-managed objects but it is almost impossible to identify all the cases, so i trying to check if there is a way to get the functionality in the previous version (without downgrading hibernate)Details:
TestControllercallsaddPaymentfromTestService1. This method is transactional.This method calls the
save()method of a repositoryThen it calls another service
TestService2method2This method performs a query using a repository and then another query from another repository which uses
EntityGraph.The exception is
While trying to reproduce the issue i got another exception, but not constantly
If we change the version of Spring Boot to 3.3.5, this works
Steps to reproduce:
Run the attached project using postgres as database.
errorCheck.zip
Access "http://localhost:8080/test" and an exception will be produced
If we change the Spring Boot version to 3.3.5 the endpoint will return the response "1"
Environment:
Spring Boot version: 3.4.0
Java version: 21
Operating System: Windows 11
