[hibernate-issues] [JIRA] (HHH-14034) session.byMultipleIds() ignores the provided graph

Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZmMxMGUyNzEx... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-14034?atlOrigin=eyJpIjoiZmMxMG... ) HHH-14034 ( https://hibernate.atlassian.net/browse/HHH-14034?atlOrigin=eyJpIjoiZmMxMG... ) session.byMultipleIds() ignores the provided graph ( https://hibernate.atlassian.net/browse/HHH-14034?atlOrigin=eyJpIjoiZmMxMG... ) Issue Type: Bug Affects Versions: 5.4.16 Assignee: Unassigned Components: hibernate-core Created: 20/May/2020 06:47 AM Fix Versions: 5.4-backlog Priority: Major Reporter: Yoann Rodière ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) As far as I can tell, the graph mentioned in the code below will always be ignored: session.byMultipleIds( Parent.class ) .with( (RootGraph) session.getEntityGraph( "eager" ), GraphSemantic.FETCH ) .multiLoad( 1, 2, 3 ); This ticket may be a duplicate of HHH-12818 ( https://hibernate.atlassian.net/browse/HHH-12818 ) Open , but honestly I can't bring myself to consider this as an "improvement" since the API to specify an entity graph already exists (but is apparently non-functional). Here is a branch with a reproducer: I also tried to start working on a fix, but this turned out to be more complex than initially anticipated. In particular: * for some reason, fetch graphs apparently don't reset eager associations to lazy; * the implementation of load graphs seem to be specific to parsed HQL queries (see org.hibernate.engine.query.spi.EntityGraphQueryHint#toFromElements , org.hibernate.hql.internal.ast.HqlSqlWalker#processQuery ), and I'm not sure how to copy that implementation to org.hibernate.loader.entity.DynamicBatchingEntityLoaderBuilder.DynamicEntityLoader.
