A-MQ resource adapter configuration problems related generic queries

Issue

• We have configuration problems/questions using AM-Q and using a MDB consuming messages running on JBoss eap-6.3.
• The AM-Q instance is running in it's own process (not embedded in JBoss).
• A resource adapter for AM-Q is deployed on JBoss and used by the MDB.
  Queries:

1. If more than one connection-definition (ConnectionFactory) are defined (in standalone.xml) for the resource adapter - which one will be used by the MDB?

2. Is it possible to define which connection-definition to use?

3. I've tried to configure the connection-definition. For example with the following, but the configuration dows not take effect:

    <config-property name="MaximumRedeliveries">
                                3
    </config-property>
    <config-property name="InitialRedeliveryDelay">
                               1000
    </config-property>
     <config-property  name="RedeliveryUseExponentialBackOff">
                                true
     </config-property>
     <config-property name="RedeliveryBackOffMultiplier">
                                5
     </config-property>

• How/where shall these configuration parameters be specified to take effect?

3. There are a number of ways to specify/override configuration parameters. In which order are they prioritized?

4. Is the client (resource adapter) doing any "local retries" (NOT going back to the AM-Q server instance)?
