Hi,

The code bellow throws SocketException with QPID 0.26 AMQP 1.0. It works fine with AMQP 0-10 client. When I add sleeps of 100ms before and after the close() calls, it works. Seems like the close() method returns too early when background threads are still not finished. The code is minimal to reproduce the problem.

Thanks for your time, Jan

...
  connection = connectionFactory.createConnection();

  // send some messages to empty queue
  for (int i = 0; i < 5; i++)
      openAndClose(connection, context);
}

static void openAndClose(Connection connection, Context context) throws JMSException,
        NamingException, InterruptedException {
    Session session = null;
    MessageProducer messageProducer = null;

    try {
        session = connection.createSession(false/*transacted*/, Session.AUTO_ACKNOWLEDGE);
        Topic topic = (Topic) context.lookup("ORDER_HISTORY_TOPIC");
        messageProducer = session.createProducer(topic);
    } finally {
        if (messageProducer != null)
            messageProducer.close();
        if (session != null)
            session.close();
    }
}
