[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5187) Allow some control over whether or not an association is loaded via a join on the merge path

[Emmanuel Bernard (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=36983#action_36983 ] 

Emmanuel Bernard commented on HHH-5187:
---------------------------------------

For the sake of completeness, here are the reasons why we do not violate the spec:
 - the specification does consider the lazy flag as optional "The <code>LAZY</code> strategy is a hint to the persistence provider runtime."
 - We (the expert group) have added the sentence "The persistence provider must not merge fields marked LAZY that have not been fetched: it must ignore such fields when merging." to make sure that lazy fields (not necessarily associations) would not be replaced by null but retain their database state. That was added after one three letter acronym vendor was expecting the lazy state to be overridden by null.
