-------------------------------
Summary: Failover with client ack mode consumer can loose a
message auto acked as a duplicate
Key: AMQ-4665
URL: https://issues.apache.org/jira/browse/AMQ-4665
Project: ActiveMQ
Issue Type: Bug
Components: JMS client
Affects Versions: 5.8.0
Reporter: Gary Tully
Assignee: Gary Tully
Fix For: 5.9.0
with a client ack consumer and failover after receipt but before message.ack
can result in a missed message when the message is redispatched and auto acked
as a duplicate.
Failover interrupt should clear dispatched and unconsumed messages so that they
can get redelivered.
auto-acking a duplicate seems over eager. think best to poison pill and now
that we can include a cause property it will be possible to differentiate.
