NullPointerException while building SessionFactory when using native sql query for loading many-to-many mapped collections -------------------------------------------------------------------------------------------------------------------------- Key: HHH-3128 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3128 Project: Hibernate3 Issue Type: Bug Affects Versions: 3.2.6, 3.2.5 Environment: Hibernate 3.2.6 Reporter: Juergen Denzel Attachments: src.zip Hi, I am trying to load a many-to-many mapped collection using a sql query like this: <sql-query name="loadItems"> <load-collection alias="item" role="test.Test.items"/> select {item.*} from Items item where item.id = :id </sql-query> This always fails due to a NullPointerException: java.lang.NullPointerException at org.hibernate.loader.custom.sql.SQLQueryParser.resolveProperties(SQLQueryParser.java:182) at org.hibernate.loader.custom.sql.SQLQueryParser.resolveCollectionProperties(SQLQueryParser.java:135) at org.hibernate.loader.custom.sql.SQLQueryParser.substituteBrackets(SQLQueryParser.java:98) at org.hibernate.loader.custom.sql.SQLQueryParser.process(SQLQueryParser.java:51) at org.hibernate.loader.custom.sql.SQLCustomQuery.<init>(SQLCustomQuery.java:110) at org.hibernate.engine.query.NativeSQLQueryPlan.<init>(NativeSQLQueryPlan.java:43) at org.hibernate.engine.query.QueryPlanCache.getNativeSQLQueryPlan(QueryPlanCache.java:114) at org.hibernate.impl.SessionFactoryImpl.checkNamedQueries(SessionFactoryImpl.java:446) at org.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:352) at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1300) at test.HibernateTest.testSessionFactory(HibernateTest.java:18) I provided a very simple TestCase + Mappings to illustrate the problem. The exception does not occur for one-to-many mappings. Just for your information, we need this functionality in order to deal with DB2 problems we have. I ran this TestCase against 3.2.5 and 3.2.6 and both failed. Thanks.
