[ http://opensource.atlassian.com/projects/hibernate/browse/HHH-5621?page=c... ] Gail Badner updated HHH-5621: ----------------------------- Description: During a session.createQuery like: Query query6 = session.createQuery("select new Something(id, event, dummyField) " + "from Something" ); A NPE is thrown: Exception in thread "main" java.lang.NullPointerException at org.hibernate.util.ReflectHelper.getConstructor(ReflectHelper.java:343) at org.hibernate.hql.ast.tree.ConstructorNode.resolveConstructor(ConstructorNode.java:176) at org.hibernate.hql.ast.tree.ConstructorNode.prepare(ConstructorNode.java:150) at org.hibernate.hql.ast.HqlSqlWalker.processConstructor(HqlSqlWalker.java:996) I join an test case. All versions of hibernate seems affected (from 3.2.6.ga to 3.6.0.RC2). This is a minor issue since an easy workaround is available: you just have to use an alias to qualifie the properties For the preceding example, we will have: Query query3 = session.createQuery("select new Something(sthg.id, sthg.event, sthg.dummyField) " + "from Something sthg" ); Possible fix: As described in the testCase, I fix this by a one character fix: In org.hibernate.hql.ast.HqlSqlWalker in method isNonQualifiedPropertyRef, change from if ( fromElements.size() == 1 ) { to if ( fromElements.size() >= 1 ) { This could means that when a property is not qualified, we leave a chance for this property to be found on the first explicit element of the from clause. I test this fix on the 3.5.5-Final code and I was able to run the test suite without failures. I can't think of a test case in which this fix could lead to a regression but I'm not an Hibernate Guru so comments are welcome. was: During a session.createQuery like: Query query6 = session.createQuery("select new Something(id, event, dummyField) " + "from Something" ); A NPE is thrown: Exception in thread "main" java.lang.NullPointerException at org.hibernate.util.ReflectHelper.getConstructor(ReflectHelper.java:343) at org.hibernate.hql.ast.tree.ConstructorNode.resolveConstructor(ConstructorNode.java:176) at org.hibernate.hql.ast.tree.ConstructorNode.prepare(ConstructorNode.java:150) at org.hibernate.hql.ast.HqlSqlWalker.processConstructor(HqlSqlWalker.java:996) I join an test case.
