Are you sure? When I try to set that property the following message is added to my server log:
[#|2007-03-12T15:46:51.305+0100|WARNING|sun-appserver-pe9.0|javax.enterprise.resource.resourceadapter|_ThreadID=13;_ThreadName=httpWorkerThread
-4848-0;RedeliveryAttempts;com.sun.messaging.jms.ra.ManagedConnectionFactory;_RequestID=536f5579-9b71-4d2e-b70e-306b31e31963;|RAR7097: No setter method present for the property RedeliveryAttempts in the class com.sun.messaging.jms.ra.ManagedConnectionFactory|#]
It also still retries once after a RuntimeException.
