-------------------------------------
Moreover (albeit a diffrent bug) changes to configurations made in standardjboss.xml
aren't loaded at startup (4.2.2 and 4.2.3)..
The resent map appears to be clears pretty much always, and hence you lose the count being
used during redelivery.. IMO if the PROPERTY_DELIVERY_COUNT doesn't exist creating it
if not present is a reasonable idea.. This saves having to set it in client code, and
pretty much the whole world uses the JMSXDeliveryCount header anyhow..
It looks like this bug has been open for over a year, and means the exceptions thrown in
MDBs cause infinite loops, which is bad, really quite seriously bad.
dlqhandler fails on redelivery for messages missing the JMS property
"JMSXDeliveryCount"

Key: EJBTHREE-1070
URL: https://jira.jboss.org/jira/browse/EJBTHREE-1070
Project: EJB 3.0
Issue Type: Bug
Affects Versions: AS 4.2.1.GA
Reporter: Danilo Guerra
GenericDLQHandler fails when handling redelivery of messages missing the property
"JMSXDeliveryCount" when using non JbossMQ providers.
excerpt from the class: org.jboss.resource.adapter.jms.inflow.dlq.GenericDLQHandler
protected boolean handleDelivery(Message msg)
{
.....
try
{
if (msg.propertyExists(PROPERTY_DELIVERY_COUNT))
count = msg.getIntProperty(PROPERTY_DELIVERY_COUNT) - 1;
}
catch (JMSException ignored)
{
count = incrementResentCounter(id);
}
...
}
This code fails because the property PROPERTY_DELIVERY_COUNT is checked and the exception
is never thrown. As a result the resent counter is not incremented and the message will
not be sent to the DLQ.
