Timothy Bish commented on AMQ-4413:
-----------------------------------
In the supplied test case the message loss is expect since persistence is not
enabled and the option to keep durable subs active is not enabled. If you
enable keepDurableSubsActive it would work as expected. What's the real
configuration you use when you encounter this problem.
> Persistent message loss when JMS durable subscriber reconnects regardless of
> message store impl.

> Key: AMQ-4413
> URL: https://issues.apache.org/jira/browse/AMQ-4413
> Project: ActiveMQ
> Issue Type: Bug
> Components: Broker, JMS client, Message Store
> Affects Versions: 5.7.0, 5.8.0
> Reporter: Jaewoong Choi
> Priority: Critical
> Attachments: AMQ4413-testcase.patch, Test.java

>
> Persistent message is lost intermittently when JMS durable topic subscriber
> reconnects to the broker service. From the log observation, it seems that
> the internal states of the store cursor (i.e. AbstractStoreCursor) is not
> well guarded by race condition between message
> sending/directly-dispatching-pending thread (from publisher) and subscription
> deactivating thread (from subscriber's closing), especially when subscriber's
> closing (javax.jms.MessageConsumer#close) and message publishing happen
> simultaneously.
> Observations and the test scenario are described at below in detail:
> http://activemq.2283324.n4.nabble.com/persistent-message-missing-to-a-durable-subscriber-when-it-reconnects-restarts-td4665130.html
> Attached please find Test.java that I used to verify this issue. I found the
> issue initially with activemq-core-5.7.0.jar then confirmed that it's
> reproducible with other upper versions (i.e. apache-activemq-5.8-SNAPSHOT,
> apache-activemq-5.9-SNAPSHOT).
> This "message loss" issue is pretty critical as it can happen whenever
> durable subscriber reconnects either purposely or unexpectedly, and it could
> be violating the one of primitive features that messaging platform
> guarantees: "no message loss", if happens, whereas it's so easy to reproduce
> the trouble.
