[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-7225) NullPointerException after persisting null entity value as natural-Id

NullPointerException after persisting null entity value as natural-Id --------------------------------------------------------------------- Key: HHH-7225 URL: https://hibernate.onjira.com/browse/HHH-7225 Project: Hibernate ORM Issue Type: Bug Components: core Affects Versions: 4.1.2 Reporter: Guenther Demetz Assignee: Steve Ebersole Priority: Minor Labels: naturalid Fix For: 4.1.3 Attachments: TestCaseHHH-7225.jar Original Estimate: 1h Time Spent: 26m Remaining Estimate: 1h This request is basically a reopening of HHH-7158. story-line: -Fixing of HHH-7158 did successfully solve both attached testmethods, but only the first one was integrated into hibernate matrix tests. -Fixing of HHH-7206 did slightly change the way how natural-id-vales are compared, causing now testmethod2 fail again. before HHH-7206: {code} // lengths have already been verified at this point for ( int i = 0; i < naturalIdTypes.length; i++ ) { if ( ! naturalIdTypes[i].isEqual( naturalIdValues[i], values[i] ) ) { return false; } } {code} after HHH-7206: (please notice now there has appeared *persister.getFactory()* as third parameter) {code} // lengths have already been verified at this point for ( int i = 0; i < naturalIdTypes.length; i++ ) { if ( ! naturalIdTypes[i].isEqual( values[i], otherValues[i], persister.getFactory() ) ) { return false; } } return true; {code} Proposed solutions: Either revert back to using the isEqual method again with 2 parameters only, or alternatevely make method EntityType#isEqual(Object x, Object y, SessionFactoryImplementor factory) stable against null x,y values as proposed in HHH-7158. I don't know which one is the better solution, but both solution make the attached testcases go through without fails.
