NPE when eager fetching joined component with native SQL query
--------------------------------------------------------------

         Key: HHH-2225
         URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2225
     Project: Hibernate3
        Type: Bug

  Components: query-sql  
    Versions: 3.2.0.ga    
    Reporter: Christian Bauer
    Priority: Minor


Item -> many-to-one -> User -> joined component -> billingAddress

This:

 result = session.createSQLQuery("select {i.*}, {u.*}, {ba.*} from ITEM i" +
                                        " join USERS u on i.SELLER_ID = u.USER_ID" +
                                        " left join BILLING_ADDRESS ba on u.USER_ID = ba.USER_ID" +
                                        " where u.USERNAME = :uname")
                         .addEntity("i", Item.class)
                         .addJoin("u", "i.seller")
                         .addJoin("ba", "u.billingAddress")

fails with:

java.lang.NullPointerException
