Hi QPID,
seemed to me, it is a bug for amqp-1-0 java client version 0.24.
I expect when amqp-1-0 client connects to amqp-0-9-1-enable broker, client
should be able to close connection because it supports amqp-1-0 only.
Actually, client could not close connection and run into deadlock because
when it sends frames for protocol handshake, on broker side broker does not
support amqp-1-0, sends back its supported version and closes TCP
connection. An unhandled exception occurs at client that causes client wait
forever.

Program to test as below

import org.apache.qpid.amqp_1_0.type.UnsignedInteger;
public class Consumer {
private static Container container = new Container();
private static String host = "localhost";
private static String remotehost = "localhost";
private static int port = 5672;
private static String username = "guest";
private static String password = "guest";
private static boolean ssl = false;
private static String queueName = "queue";
public static void main(String[] args) {
Consumer consumer = new Consumer();
consumer.receive();
}
public void receive() {
try {
Connection conn = new Connection(host, port, username,
password, 65536,
container, remotehost, ssl, -1);
Session session = conn.createSession();
Receiver r = session.createReceiver(queueName,
AcknowledgeMode.ALO, null,
true, null, null);
r.setCredit(UnsignedInteger.valueOf(100), false);
for (;;) {
Message m = r.receive(10000L);
if (m == null) {
break;
}
r.acknowledgeAll(m);
System.out.println("Received Message : " +
m.getPayload());
}
r.close();
r.getSession().close();
r.getSession().getConnection().close();
} catch (ConnectionException e) {
e.printStackTrace();
}
}
}
