------------------------------------
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)

{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.
