NullPointerException from AnnotationConfiguration with specific order of calling addResource and addPackage when package-info.java present ------------------------------------------------------------------------------------------------------------------------------------------ Key: ANN-608 URL: http://opensource.atlassian.com/projects/hibernate/browse/ANN-608 Project: Hibernate Annotations Issue Type: Bug Affects Versions: 3.3.0.ga Environment: Hibernate 3.2.3 Reporter: Steve Gilbert Fix For: 3.3.1 Attachments: Main.java, orm.xml, package-info.java There is a bug in AnnotationConfiguration that causes a NullPointerException. I have attached several files: orm.xml, Main.java, package-info.java. The problem is caused by the order of the addResource and addPackage calls in combination with having a package-info.java file with some contents. If the addPackage is called before the addResource, or if the GenericGenerator annotation in the package info file is removed, there is no problem. I cannot change the order of those calls for my production code, however, because Spring is being used to create the SessionFactory and it calls the methods in that order: resource followed by package. There appears to be a problem with initializing org.hibernate.cfg.annotations.reflection.EJB3OverridenAnnotationReader. When this call is made on line 360: annotationsMap.put( ann.annotationType(), ann ); the map is null. Inserting a creation for the map, (borrowed from elsewhere in the method) on line 359, before the "for" statement: annotationsMap = new HashMap<Class, Annotation>( annotations.length + 5 ); resolves the problem.
