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

[Emmanuel Bernard (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5543?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=38335#action_38335 ] 

Emmanuel Bernard commented on HHH-5543:
---------------------------------------

The only thing that rings a bell is that the code might use the file name for better error handling down the road but if you ahve not encountered that in the code path, that should be fine.

> 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.
