> Key: OPENJPA-2925
> URL: https://issues.apache.org/jira/browse/OPENJPA-2925
> Project: OpenJPA
> Issue Type: Bug
> Affects Versions: 3.2.2, 4.0.0
> Reporter: Juho Rinta-Paavola
> Priority: Major
>
> Given the entities
> {code:java}
> @Entity
> public class Cat {
> @Id
> @GeneratedValue
> private int id;
> @OneToMany(mappedBy = "parent", fetch = FetchType.EAGER)
> private List<Cat> children = new ArrayList<>();
> @ManyToOne
> private Cat parent;
> @ManyToOne
> private Human human;
> }{code}
> and
> {code:java}
> @Entity
> public class Human {
> @Id
> @GeneratedValue
> private int id;
> private String name;
> @OneToMany(mappedBy = "human", fetch = FetchType.EAGER)
> private List<Cat> cats = new ArrayList<>();
> } {code}
> Calling {{kitten.getParent().getHuman()}} will return the kitten's human
> instead of the expected parent's human, if the kitten has a sibling and both
> kittens belong to the same human.
> Failing unit test is available at
> https://github.com/jrp6/openjpa/blob/openjpa-2925/openjpa-persistence-jdbc/src/test/java/org/apache/openjpa/persistence/recursive/TestRecursiveThenNonRecursiveRelationship.java
