Keith Wall commented on QPID-7153:
----------------------------------
One comment. If as a user I want the expired messages that that land on the
DLQ to live indefinitely, then I would have expected to set the the DLQ's
{{minimumMessageTtl}} to {{Long.MAX_VALUE}}. This doesn't work because the
long arithmetic overflows within {{AbstactQueue#calculateExpiration}} and
{{wouldExpire}} (which would be better named wouldExpireNow) returns the wrong
value. Perhaps {{calculateExpiration}} should use {{Math.addExact}} and clamp
the value if ArithmeticException occurs.
Separately, largely note to self, when testing this feature with the Qpid JMS
Client, one needs to remember to turn off {{jms.localMessageExpiry}} otherwise
the client expires the message as it is consumed from the DLQ.
> Allow expired messages to be sent to DLQ

> Currently the Java Broker simply discards messages that expire (TTL). The
> behaviour should be configurable and allow for expired messages to be
> directed to the alternate exchange to allow for dead-lettering.
