Subject [jira] Created: (AMQ-2630) NullPointerException in ActiveMQDestination (with patch)

NullPointerException in ActiveMQDestination (with patch)
--------------------------------------------------------

                 Key: AMQ-2630
                 URL: https://issues.apache.org/activemq/browse/AMQ-2630
             Project: ActiveMQ
          Issue Type: Bug
            Reporter: juergen schmied
             Fix For: 5.4.0
         Attachments: Destination.patch

The Oracle AQjmsDestination Object implements all the interfaces:

AQjmsDestination
 <-Queue<-Destination
 <-TemporaryQueue<-Queue<-Destination
 <-TemporaryTopicTopic<-Destination
 <-Topic<-Destination

The function ActiveMQDestination.transform fails to indicate the type of the Destination Object
right, because it implements all Interfaces.

When the Object its a Topic in reality, the

        if (dest instanceof TemporaryQueue) {
            return new ActiveMQTempQueue(((TemporaryQueue)dest).getQueueName());
        }

thinks its a TemporaryQueue.

This causes the following stacktrace:
java.lang.NullPointerException
