Here is an overview of the issue:
---------------------------------------------------------------------
        Key: HB-262
    Summary: NullPointerException while loading 2.0.2 working mapping
       Type: Bug

     Status: Unassigned
   Priority: Minor

    Project: Hibernate2
 Components: 
             core
   Fix Fors:
             2.1 beta 2
   Versions:
             2.1 beta 1

    Updated: Fri, 15 Aug 2003 8:21 AM
Environment: Linux JDK 1.4.2

Description:
java.lang.NullPointerException
        at net.sf.hibernate.persister.NormalizedEntityPersister.getIdentifierColumnNames(NormalizedEntityPersister.java:1075)
	at net.sf.hibernate.persister.AbstractEntityPersister.(AbstractEntityPersister.java:699)
	at net.sf.hibernate.persister.NormalizedEntityPersister.(NormalizedEntityPersister.java:646)
	at net.sf.hibernate.persister.PersisterFactory.create(PersisterFactory.java:32)
	at net.sf.hibernate.impl.SessionFactoryImpl.(SessionFactoryImpl.java:137)
	at net.sf.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:647)

This mapping works with 2.0.2, I tried 2.1 beta 1 as a drop-in replacement for our medium sized project:

    <class name="test.Connection" table="connections">

        <id name="OID" type="string">
            <column name="connection_id" sql-type="char(32)"/>
            <generator class="uuid.hex"/>
        </id>

        <version name="version"/>

        <joined-subclass name="test.Internet" table="internet">
            <key>
                <column name="connection_id" sql-type="char(32)"/>
            </key>
        </joined-subclass>

    </class>

The error ocours with the joined subclass mapping.
