There seems to be a regression in 5.3.X from previous versions when using a OneToMany relation with referencedColumnName and EAGER fetching.

When fetching an parent instance with one or many children, Hibernate return a random number of entities.

Parent:

@Id
@Column(name = "PARENT_ID")
private Long id;

@OneToMany(fetch = FetchType.EAGER, cascade =

)
@JoinColumn(name = "PARENT_ID", referencedColumnName = "PARENT_ID")
@OrderBy("createdOn desc")
private List<Child> children;

Child:

@Id
@Column(name = "CHILD_ID")
private Long id;

@Column(name = "PARENT_ID")
private Long parentId;

@Column(name = "CREATED_ON")
private ZonedDateTime createdOn;

When adding 2 children and 1 parent to the databse, we end up with a List of 26 children in the parent.

This is fairly old code and could be done much better, but up to 5.3.X this worked fine.

This has been tested with Postgresql, Oracle and H2 in memory and is always reproducible.

I have attached a test (maven setup).
