[hibernate-issues] [Hibernate-JIRA] Created: (HHH-6718) Non-cascaded lazy association loaded during merge

Non-cascaded lazy association loaded during merge ------------------------------------------------- Key: HHH-6718 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-6718 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.6.7, 3.6.6, 3.6.5 Environment: Derby & Oracle database Reporter: Reto Urfer Attachments: bug.zip Scenario: - Class A, B and C, no secondary cache - OneToOne association between A and B, not cascaded, eagerly loaded - OneToOne association between B and C, all cascaded, lazy loaded If I retrieve A by id, only A and the associated B are loaded, which is completly what i expected. If I modify A when the instance is detached and later merge it again then A and the associated B are loaded but together with B also C is loaded within a left outer join. This results in very heavy performance impacts within our application. I have added a zip file with a simple test case to reproduce the problem -- This message is automatically generated by JIRA.
