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
