It does.

If you check your log, you will see an ERROR, where the XML validation fails.

Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-328
    Summary: NullPointerException from buildSessionFactory
       Type: Bug

     Status: Closed
   Priority: Major
 Resolution: REJECTED

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0.2

Environment: MacOS X 10.1.5 JDK 1.3

Description:
I got a NullPointerException with this stack trace:

Exception in thread "main" java.lang.NullPointerException
        at net.sf.hibernate.collection.CollectionPersister.<init>(CollectionPersister.java:191)
        at net.sf.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:216)
        at net.sf.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:627)
        at com.loren.Report.startHibernate(Report.java:44)
        at com.loren.Report.main(Report.java:88)

Turned out the problem was a missing 'index' attribute on a 'map' in a hibernate mapping file:

    <map name="documentAuthors" table="document_author" sort="com.loren.DocumentAuthorComparator" inverse="true" lazy="true">
        <key column="document"/>
        <index column="place" type="int"/>
        <one-to-many class="com.loren.DocumentAuthor"/>
     </map>

(This is the corrected version.)

Hibernate should give a specific error message in this situation.
