Upgrade To Hibernate 4.3.4 main method never terminates JVM not finish

Question

i have to upgrade from Hibernate 4.2.3 to Hibernate 4.3.4 to test some JPA 2.1 Spec. i have only change this line of code

Previous line:

final org.hibernate.service.ServiceRegistry serviceRegistry = new org.hibernate.service.ServiceRegistryBuilder().applySettings(hibConfiguration.getProperties()).buildServiceRegistry();

new Added code line

final org.hibernate.service.ServiceRegistry serviceRegistry = new org.hibernate.boot.registry.StandardServiceRegistryBuilder().applySettings(hibConfiguration.getProperties()).build();

the problem i have a main method just for test some Criteria API but the main method never finish with the latest Hibernate Version i have retrieve the running threads and and with the latest version the threads are as follow.

ThreadList:
[threadID:]2  [threadName:] Reference Handler [isDaemon:] true [isAlive:] true
[threadID:]3  [threadName:] Finalizer [isDaemon:] true [isAlive:] true
[threadID:]4  [threadName:] Signal Dispatcher [isDaemon:] true [isAlive:] true
[threadID:]5  [threadName:] Attach Listener [isDaemon:] true [isAlive:] true
[threadID:]10 [threadName:] Abandoned connection cleanup thread [isDaemon:] true [isAlive:] true
[threadID:]11 [threadName:] pool-1-thread-1 [isDaemon:] false [isAlive:] true
[threadID:]1  [threadName:] main [isDaemon:] false [isAlive:] true

comparing with the previous version this thread is the new one.

[threadID:]11 [threadName:] pool-1-thread-1 [isDaemon:] false [isAlive:] true

is a not a daemon according to the spec.

No, it is not. The virtual machine terminates if the last non-daemon thread has finished. It doesn't have to be the main thread.

i think this thread will not finish at least in 5 minutes.

the problem arises only creating the HibernateSessionFactory.

public static void main(String[] args)
{        
    HibernateHandler handler = new HibernateHandler(true);//creates the HibernateSessionFactory
    return;//JVM not finish at this point
}

i want my JVM terminates with the main method finish..

what i am doing wrong..

Answer 1

Seems that new ServiceRegister is not closed,Destroyed when SessionFactory is closed you have to destroy by yourself when you call.

getSessionFactory.close().

my new Hibernate Code

final Configuration hibConfiguration = new Configuration().configure(yourCFGPath);         
final org.hibernate.service.ServiceRegistry serviceRegistry = new org.hibernate.boot.registry
.StandardServiceRegistryBuilder().
applySettings(hibConfiguration.getProperties()).build();
hibConfiguration.setSessionFactoryObserver(new SessionFactoryObserver()
{
    @Override
    public void sessionFactoryCreated(SessionFactory factory){}
    @Override
    public void sessionFactoryClosed(SessionFactory factory)
    {
        ((StandardServiceRegistryImpl)serviceRegistry).destroy();
    }});                
 final org.hibernate.SessionFactory factory = hibConfiguration.buildSessionFactory(serviceRegistry);

later you have to call

session.getSessionFactory().close();

i hope really helps somebody.

To find out what the thread is doing, you can take a thread dump, for instance by running your program from eclipse in debug mode, and suspending the thread.

In your specific case though, you should try invoking sessionFactory.close().
