Why redelivery ResourceAdapter Config is not respected when defined in more than one config.

Issue

• Why the activation spec properties[1] "RedeliveryBackOffMultiplier" and "RedeliveryUseExponentialBackOff" can not be used within @ActivationConfigProperty. In contrast, it accepts "backOffMultiplier" and "useExponentialBackOff". http://activemq.apache.org/resource-adapter-properties.html
