[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4661) Properly propagate Query.setLockMode to Hibernate Core

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4661?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=35322#action_35322 ] 

Steve Ebersole commented on HHH-4661:
-------------------------------------

What is the exact semantic here in terms of what to lock?  Hibernate query locking is based on the individual "identification variables".  In others words given an HQL query "from Animal a join fetch a.friends", setLockMode( "a", someLockMode ) only affects the lockmode of the root return because it is only applied to the root from via its alias.  

What is the rule for this in JPA ql/criterias?
