[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=38331#action_38331 ] 

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

If I understand correctly, after the call to {{addXMLEntities}} we no longer really need the local {{List<String> xmlFiles}} variable for anything other than to pass it to (eventually) {{addClassesToSessionFactory}} so that they get added to the configuration.  Seems to me the solution here is to save the parsed and validated DOM tree, once that code is fixed up ( see HHH-5310 ), and pass that DOM tree into the config via a method that indicates it has already been validated.

> 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.
