AMQ 7.0.3.GA
active/active cluster with two brokers
A message was sent to a queue using AMQP 1.0 to broker1. A client at broker2 tried to read it.
But broker2 throws an exception and the message is not sent to the client:

The queue is not created on the fly but configured in the brokers, both brokers have this config:
<queues>
<queue name="awe.test.queue">
<address>awe.test.queue</address>
<durable>true</durable>
</queue>
</queues>
The cluster configuration is pretty much copied from the examples:
<!-- Clustering configuration -->
<broadcast-groups>
<broadcast-group name="my-broadcast-group">
<group-address>${udp-address:231.7.7.7}</group-address>
<group-port>9876</group-port>

qpid-send and qpid-receive were used as test clients. Sending is done like:
qpid-send -b localhost:9800 -a awe.test.queue '--connection-option={protocol:amqp1.0}' --content-string 'test message Do 7. Dez 09:31:51 CET 2017' --durable=yes
Grabbed the message from the logfile. It looks like this:
0 -> @transfer(20) [handle=0, delivery-id=0, delivery-tag=b"\x00\x00\x00\x00", message-format=0, settled=false, more=false] (79) "\x00Sp\xc0\x04\x02AP\x00\x00St\xc1\x14\x04\xa1\x02snR\x01\xa1\x02ts\x81\x14\xfd\xf8\xcb\xdaG\x94U\x00Sw\xa1(test message Do 7. Dez 09:31:51 CET 2017"
Reading is done using:
qpid-receive -b localhost:9802 -a awe.test.queue '--connection-option={protocol:amqp1.0}' -t --timeout 500
I can see, that AMQPMessage.getAddress() can return null:
@Override public String getAddress() { if (address == null) { Properties properties = getProtonMessage().getProperties(); if (properties != null) { return properties.getTo(); } else { return null; } } else { return address; } }
But ServerSessionImpl.send() does not check for null, but it should. This is because SimpleString.toSimpleString() can return null if the input is null:
SimpleString address = message.getAddressSimpleString();
if (defaultAddress == null && address != null) {
defaultAddress = address;
}
if (address == null) {
// We don't want to force a re-encode when the message gets sent to the consumer
message.setAddress(defaultAddress);
}
SimpleString:
public static SimpleString toSimpleString(final String string) { if (string == null) { return null; } return new SimpleString(string); }
