Summary: JMS message lost on restart
Initial Comment:
Hello all,
the following problem occurs on both JBoss 3.2.1 and
3.2.2RC3. I'm running Sun VM 1.4.1_03-b02 on Win2K Pro.
With a MDB which listens on a queue using the file
based PM, when the server is stopped and started again
while JMS are left to consume, exactly one message is lost.
To reproduce, set up a simple client and MDB. The
client connects to the queue and sends some 50
persistent messages (with an increasing number) to the
queue. The MDB's onMessage() method does nothing but to
trace the received message and sleep for 10 seconds.
When the server is stopped (Ctrl-C) before all messages
were consumed, all messages not consumed yet can be
found in the persistence directory for the queue,
except the message immediately following the latest
consumed message (Dead letter queue is empty).
If the server is restarted, the remaining persisted
messages are processed, but one message is lost.
Also see files in attached ZIP archive:
- server trace for server 1 (before restart)
- server trace for server 2 (after restart)
- source for the client
- source and XML files MDB
- relevant server configuration files
In the example files, message no. 16 is lost.
BTW: the exception in the server 1 trace:
16:24:59,232 ERROR [JMSContainerInvoker] Exception in
JMSCI message listener
java.lang.NullPointerException

occurs on shutdown and looks just like the exception
mentioned in bug no. 781687 - I thought the bug was
already fixed (or didnt the fix make in in 3.2.2RC3)?
