When using multiple address settings in HornetQ configuration the address setting should be inherited from more generic setting by more specific setting. If two address setting are used like
<address-settings>
                    <address-setting match="#">
                        <dead-letter-address>jms.queue.DLQ</dead-letter-address>
                        <expiry-address>jms.queue.ExpiryQueue</expiry-address>
                        <redelivery-delay>0</redelivery-delay>
                        <max-delivery-attempts>5</max-delivery-attempts>
                        <max-size-bytes>10485760</max-size-bytes>
                        <page-size-bytes>2097152</page-size-bytes>
                        <address-full-policy>PAGE</address-full-policy>
                        <message-counter-history-day-limit>10</message-counter-history-day-limit>
                    </address-setting>
                    <address-setting match="jms.queue.testQueue">
                        <dead-letter-address>jms.queue.DLQ</dead-letter-address>
                        <expiry-address>jms.queue.ExpiryQueue</expiry-address>
                        <redelivery-delay>0</redelivery-delay>
                        <max-size-bytes>10485760</max-size-bytes>
                        <page-size-bytes>2097152</page-size-bytes>
                        <address-full-policy>PAGE</address-full-policy>
                        <message-counter-history-day-limit>10</message-counter-history-day-limit>
                    </address-setting>
                </address-settings>
It is expected that the setting for jms.queue.testQueue would inherit max-delivery-attempts from default address setting "#" but it does not. Instead if uses the default value for max-delivery-attempts which is 9.
