Hibernate version:3.2

Name and version of the database you are using:HSQLDB 1.8


When I execute the following sequence...

//using "Transaction demarcation with plain JDBC"
config.setProperty("hibernate.current_session_context_class","thread");
config.setProperty("hibernate.transaction.factory_class","org.hibernate.transaction.JDBCTransactionFactory");

sf = config.buildSessionFactory();
sf.getCurrentSession().beginTransaction();
sf.getCurrentSession().rollback(); // session automatically closed
sf.close()

sf = config.buildSessionFactory();

The 2nd buildSessionFactory() throws a DuplicateMappingException.
Does the session factory close() not remove all the existing mapping as well?

Full stack trace of any exception that occurs:

org.hibernate.DuplicateMappingException: Duplicate class/entity mapping com.abc.Feature
at org.hibernate.cfg.Mappings.addClass(Mappings.java:118)
at org.hibernate.cfg.AnnotationBinder.bindClass(AnnotationBinder.java:769)
at org.hibernate.cfg.AnnotationConfiguration.processArtifactsOfType(AnnotationConfiguration.java:498)
at org.hibernate.cfg.AnnotationConfiguration.secondPassCompile(AnnotationConfiguration.java:277)
at org.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:1210)
at org.hibernate.cfg.AnnotationConfiguration.buildSessionFactory(AnnotationConfiguration.java:915)

Notice the error comes from org.hibernate.cfg. The original Configuration isn't explicitly single-use. You're using AnnotationConfiguration which looks like it is behaving that way. You might have some luck creating a JIRA for this, though it is a pretty rare use case I believe.
