             Summary: Sjms with Artemis causes NullPointerException due to a ClassCastException
                 Key: CAMEL-11772
                 URL: https://issues.apache.org/jira/browse/CAMEL-11772
             Project: Camel
          Issue Type: Bug
          Components: camel-sjms
    Affects Versions: 2.19.2, 2.19.1, 2.19.0
            Reporter: Derek Wilhelm


When using a camel-sjms endpoint with an Apache Artemis broker, the sjms endpoint will throw
a NullPointerException in the org.apache.camel.component.sjms.consumer.AbstractMessageHandler.onMessage
method.  However, this exception is actually masking the real exception within sjms.  In SjmsMessage.java
the method getDestinationAsString gets called with a javax.jms.Destination object.  In this
case, it is a org.apache.activemq.artemis.jms.client.ActiveMQDestination.  The ActiveMQDestination
is neither a javax.jms.Topic nor a javax.jms.Queue.  In the getDestinationAsString method
in SjmsMessage.java, it first checks to see if the destination is a Topic and then if it is
not it blindly casts to a javax.jms.Queue and in this case causes a ClassCastException.
