[hibernate-issues] [Hibernate-JIRA] Resolved: (HHH-2542) NullPointerException in TypeFactory.replaceAssociations for ComponentType

NullPointerException in TypeFactory.replaceAssociations for ComponentType ------------------------------------------------------------------------- Key: HHH-2542 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2542 Project: Hibernate3 Issue Type: Bug Components: core Affects Versions: 3.2.3 Reporter: Reto Urfer Assignee: Gail Badner Fix For: 3.2.6, 3.3 Attachments: HHH-2542.patch, Hibernate Bug 2542.zip The following code block will throw a NullPointerException when targetComponentValues should be determines and target[i] contains a NULL value. else if ( types[i].isComponentType() ) { // need to extract the component values and check for subtype replacements... AbstractComponentType componentType = ( AbstractComponentType ) types[i]; Type[] subtypes = componentType.getSubtypes(); Object[] origComponentValues = original[i] == null ? new Object[subtypes.length] : componentType.getPropertyValues( original[i], session ); Object[] targetComponentValues = componentType.getPropertyValues( target[i], session ); replaceAssociations( origComponentValues, targetComponentValues, subtypes, session, null, copyCache, foreignKeyDirection ); This problem can be fixed the same way as it is prevented when origComponentValues are determined (see following line) Object[] targetComponentValues = target[i] == null ? new Object[subtypes.length] : componentType.getPropertyValues( target[i], session ); copied[i] = target[i]; } The problem did not exist in Version 3.2.2
