JPA stackoverflow error when fetching data

I have 2 entities namely Teacher and Club, I need to retrieve the teacher data along with its related club and/or sports.
I a bit new to JPA so am having trouble debugging the stack overflow error I get when I use the findAll method on the Teacher repository.
I had tried adding #JsonIgnore annotation to my one-to-many annotation to deal with the recursion problem as suggested in some similar questions but was still getting problems and am not sure how exactly it's supposed to solve the problem.

Spring Boot JpaRepository save call doesn't seem to be doing anything

I'm writing a Spring Boot application that uses JpaRepository interfaces. In a service method where I'm attempting to write some objects, calls to two repositories' save() methods don't appear to be doing anything, but are also not throwing any exceptions.
I'm using mysql, with ISAM tables, with MySQL5Dialect.

According to what I've read on the subject, methods annotated with #Transactional should commit once the method returns. When I execute the method, it does in fact print to the log that it's saving. However, I have sql debugging turned on, and it does not print any sql statements when it saves. (it does print sql statements on selects.)
The method has no problems doing the selects above, only the saves in the latter part. No exceptions are thrown, but the data doesn't appear in the tables that the entities are using. The only line that gets printed in the log for each save looks like this:
o.s.t.i.TransactionInterceptor : Completing transaction for [org.springframework.data.jpa.repository.support.SimpleJpaRepository.save]
I'm not sure if this is relevant, but this call is made by the listener class for a jms queue.
My question is, am I missing anything to enable persisting data in this way? From what I've read, #Transactional automatically has readOnly set to true, and my IDE confirms this. Did I miss something important?

For anyone reading this in the future, the root cause of the issue was that the service method call was coming from a message queue receiver class. I'm not sure why. When I moved the call directly to the web service instead of the queue receiver, the insert happened with no issues.

Did someone have a similar problem?
Is there any solution?
Is possible this is bug ?!

1) You put #Id and #Column annotations on the entity class only. Do not put them in the ILbgEntityPK class.
2) Do not add setters in the id class.. create a constructor accepting the id fields.
3) When defining the #JoinColumns try to use database column names, not entity field names:
#OneToMany(targetEntity = ILbgEntity.class,fetch = FetchType.LAZY)
#JoinColumns({#JoinColumn(name = "sid_o",referencedColumnName = "sid_o",insertable = false,updatable = false),
#JoinColumn(name = "pnr_o" ,referencedColumnName = "pnr_o",insertable = false,updatable = false)})

Use below code in case of #OneToMany
#OneToMany(targetEntity = ILbgEntity.class, orphanRemoval = true, cascade = { CascadeType.ALL, CascadeType.REMOVE })
#JoinColumn(name = "sid_o", nullable = false)
#LazyCollection(LazyCollectionOption.FALSE)
#Fetch(FetchMode.SUBSELECT)

Hibernate #OneToMany fails with "collection is not associated with any session"

Here's the point: I want to load "DeliveryOrderEntity" (code below) from DB (MySQL). It has 1 foreign key with "one-to-many" relationship. It connects "BillsEntity" using billNumber. To make it clear - I have table ORDER with column BILL_NUMBER and table BILL with columns BILL_ID (primary key) and BILL_NUMBER (column, that connects BILL with ORDER).
Here is my code:
DeliveryOrderEntity.java:
#Entity

As you can see, I have unidirectional OneToMany relationship. The problem is that when i have 2 rows in DELIVERY_ORDER table with the same BILL_NUMBER and I try to get list of orders - it fails with:

Here is the code where i fetch the list:
public List<DeliveryOrderEntity> listOrders() {
List findAllOrders = new ArrayList();
EntityManager entityManager = transactionManager.getEntityManagerFactory().createEntityManager();
try {
entityManager.getTransaction().begin();
findAllOrders = entityManager.createNamedQuery("findAllOrders").getResultList();
} catch (Exception e) {
e.printStackTrace();
} finally {
entityManager.getTransaction().commit();
}
return findAllOrders;
}
Thank you in advance.

I apologize for the fields naes in French.
Now, when I try to catch all of the entities:
List l = session.createCriteria(CategoriesDuSpectacle.class).list();
This works fine.
But when I try to add a criteria:
l = session.createCriteria(CategoriesDuSpectacle.class).add(Restrictions.ilike("commentaire", "a")).list();
I get the following error:
org.hibernate.QueryException: could not resolve property: commentaire of: entities.CategoriesDuSpectacle
This sounds strange to me as the concerned field is mentionned in CategoriesDuSpectacle class:
#EmbeddedId
#AttributeOverrides({
{...}
#AttributeOverride(name = "commentaire", column = #Column(name = "Commentaire")),
{...}
})
Any idea about what I missed?
Thx in advance.

a good night made me figure it out.
I used the parameter on the wrong object:
l = session.createCriteria(CategoriesDuSpectacle.class).add(Restrictions.ilike("commentaire", "a")).list();
While it should have been this way:
l = session.createCriteria(CategoriesDuSpectacle.class).add(Restrictions.ilike("id.commentaire", "a")).list();
Hope it will help someone else.
