Sébastien Tardif, as I said on a [comment|https://hibernate.atlassian.net/browse/HHH-4297?focusedCommentId=101128&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-101128) on HHH-4297 Open , the query you are using is not valid.

The attached test passes if the following invalid query:

select m.employees from Manager m

is changed to a valid query:

select e from Manager m join m.employees e
