[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-5543) JEE bootstrapping should only parse and validate mapping files once

[Steve Ebersole (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38336#action_38336 ] 

Steve Ebersole commented on HHH-5543:
-------------------------------------

This is handled much differently on trunk.  In 3.5 and prior eventually you always added a {{Document}} to the {{Configuration}}, which of course lost the ability to report on source file names.  I improved that in 3.6 to use a custom {{XmlDocument}} instead that wraps the {{Document}} with some other information called an {{Origin}}.

So I'll roll this change back on the 3.5 branch.

> Currently mapping files get parsed and validated twice during JEE bootstrapping:
> # once in {{org.hibernate.ejb.Ejb3Configuration#addXMLEntities}} (from {{org.hibernate.ejb.Ejb3Configuration#configure}}, from {{org.hibernate.ejb.HibernatePersistence#createContainerEntityManagerFactory}}) 
> # again to actually add it to the configuration from {{org.hibernate.ejb.Ejb3Configuration#addClassesToSessionFactory}} (from {{org.hibernate.ejb.Ejb3Configuration#configure}}, from {{org.hibernate.ejb.HibernatePersistence#createContainerEntityManagerFactory}})
> AFAICT, the first occurrence is used to identify classes for potential enhancement.
