----------------------------------
Summary: 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: 5.8.0, 5.7.0
Reporter: Jaewoong Choi
Priority: Critical
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
I have a simple Test.java file that I used to verify this issue (I'll attach
this file). I encountered this problem 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's violating the
one of primitive features that messaging platform guarantees when it happens,
whereas it's so easy to reproduce the trouble.
