Nevin Chen created AMQ-6054:
-------------------------------
Summary: Durable subscriber cannot receive the existing messages
after AMQ restarts
Key: AMQ-6054
URL: https://issues.apache.org/jira/browse/AMQ-6054
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.12.1
Environment: Redhat Linux
Reporter: Nevin Chen
*How to Reproduce*
1. Make a durable subscription to a topic from a JMS client.
2. Disconnect the JMS client.
3. Send a message to the subscribed topic from another JMS client.
4. Restart AMQ.
5. When the duarable re-connects to AMQ, it cannot receive the message sent in
step 3.
*Cause Analysis*
The message is saved in the persistent store successfully. However, when the
message is marshalled by the class MessageMarshaller, the field
regionDestination is not marshalled and saved to persistent store. When the
message is recovered from persistent store after restart, the regionDestination
filed of Message is empty so it is unknown which topic this message belongs to.
*Possible Cause*
In the method
org.apache.activemq.broker.region.Topic.activate(ConnectionContext context,
final DurableTopicSubscription subscription), the
subscription.isRecoveryRequired() check is always false. The message cannot go
to the subscription.
