Description Jiri Sedlacek 2011-09-29 09:13:43 UTC 
Description of problem: When qpidd is killed and restarted while messages are received by MDB, MDB receives and stores more messages, that was sent.


Steps to Reproduce:
1. checkout https://svn.devel.redhat.com/repos/jboss-qa/mrg/tests/ha
2. fix annotation in
/mdb-ejb/src/main/java/org/jboss/test/mdb/MRGJCAMessageBean.java to point to
your MRG server
3. replace hibernate dialect in /mdb-ejb/src/main/resources/META-INF/persistence.xml (if you use another db then mysql51)
4. compile with mvn -DskipTests clean package
5. configure eap to use mysql51 db for defaultDS and defaultXADS (or another db with xa transactions support)
6. copy ha/mdb-test/target/ha-kill-mrg-test.ear to deploy directory of EAP 5.1.1
(profile production)
7. checkout https://svn.devel.redhat.com/repos/jboss-qa/mrg/qpid-java-jca
8. configure qpid-java-jca/qpid-jca-ds.xml to point to your MRG server and copy it with qpid-ra.rar to deploy directory of eap production profile
9. start mrg enabled to store messages through restart
10. Start EAP
11. Go to http://localhost:8080/servlet/mrgtest?op=send&count=1000 - this sends 1000 messages to queue, that is consumed by mdb
12. while the mdb receives messages, kill qpidd daemon and restart it, eap should reconnect. 
13. after all messages are processed, check number of messages in db by http://localhost:8080/servlet/mrgtest?op=get-count, in db will be more messages that it was sent.
  
Actual results:

Received more messages, that were sent.

Expected results:

To receive exact amount of messages (number, which was sent)

From my analysis, I believe this is an issue with the JMS client issuing 'extra-credits' on redelivery. As such, I don't believe this will be fixed in time for the 2.0.4 release. Also, I am changing the component to qpid-java as this is a client issue and does not involve the adapter directly.

This has been addressed in the latest release. I am closing this as a result.
