             Summary: NPE when deploying 2 MDBs with same clientID/subscriptionName
                 Key: ARTEMIS-1475
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1475
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: Broker
    Affects Versions: 1.5.5
            Reporter: Jeff Mesnil


Steps to reproduce:

* deploy an application in an app server using the Artemis Resource adapters with 2 MDBs that have the same clientID and subscriptionName activation config properties:

{code}
@MessageDriven(name = "HelloWorldQTopicMDB2", activationConfig = {
        @ActivationConfigProperty(propertyName = "destinationLookup", propertyValue = "topic/HELLOWORLDMDBTopic"),
        @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Topic"),
        @ActivationConfigProperty(propertyName = "subscriptionName", propertyValue = "mySubscription"),
        @ActivationConfigProperty(propertyName = "clientID", propertyValue = "myClientId"),
        @ActivationConfigProperty(propertyName = "subscriptionDurability", propertyValue = "Durable"),
        @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge")})
{code}

Result:
* when the application is deployed, it fails with the error: 
{code}
13:38:40,187 ERROR [org.apache.activemq.artemis.ra] (default-threads - 3) AMQ154003: Unable to reconnect org.apache.activemq.artemis.ra.inflow.ActiveMQActivatio
nSpec(ra=org.wildfly.extension.messaging.activemq.ActiveMQResourceAdapter@2bd07716 destination=topic/HELLOWORLDMDBTopic destinationType=javax.jms.Topic ack=Auto
-acknowledge durable=true clientID=myClientId subscription=mySubscription user=null maxSession=15): java.lang.NullPointerException
        at org.apache.activemq.artemis.ra.inflow.ActiveMQMessageHandler.setup(ActiveMQMessageHandler.java:125)
        at org.apache.activemq.artemis.ra.inflow.ActiveMQActivation.setup(ActiveMQActivation.java:314)
        at org.apache.activemq.artemis.ra.inflow.ActiveMQActivation.reconnect(ActiveMQActivation.java:658)
        at org.apache.activemq.artemis.ra.inflow.ActiveMQActivation$SetupActivation.run(ActiveMQActivation.java:698)
{code}

Expected outcome:

The deployment should fail with the correct exception from throw new javax.jms.IllegalStateException("Cannot create a subscriber on the durable subscription since it already has subscriber(s)");
          
The NPE is caused by ActiveMQActivationSpec#shareSubscriptions that is not instantiated to false in the default constructor.

In addition, the error message should be i18nized.
