Issue Type: Bug Affects Versions: 5.4.19 Assignee: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A58fa1ced-171a-4c00-97e8-5d70d442cc4b ) Components: hibernate-core Created: 29/Jul/2020 02:45 AM Fix Versions: 5.4-backlog Priority: Major Reporter: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%3A58fa1ced-171a-4c00-97e8-5d70d442cc4b )

When I apply a fetch graph to a query, it is correctly applied to the first result: eager associations that are not mentioned in the fetch graph are overridden and made lazy.

However, this is not true for results beyond the first one (index 1, 2, etc.): for those results, eager associations are loaded eagerly, even if they are not mentioned in the fetch graph.

This used to work in 5.4.18.Final.

PR coming, with a test case and hopefully a fix.
