Michael Glauche created OPENJPA-2303:
----------------------------------------
Summary: second call of getSingleResult() fails with
@EagerFetchMode(FetchMode.JOIN)
Key: OPENJPA-2303
URL: https://issues.apache.org/jira/browse/OPENJPA-2303
Project: OpenJPA
Issue Type: Bug
Affects Versions: 2.2.1, 2.2.0
Reporter: Michael Glauche
When an entity with a field like this:
@OneToMany(mappedBy="parent", fetch=FetchType.EAGER)
@EagerFetchMode(FetchMode.JOIN)
is loaded with getSingleResult() for the second time, an Exception is thrown:
javax.persistence.NonUniqueResultException: Query "select A from EntityA A
where A.id=1" selected 3 results, but expected unique result.
When i remove the @EagerFetchMode annotation everything works fine (but then
n+1 selects are fired to load EntityA)
See attached Test Project.
