  </Trace>
  
  This is due to ActiveMQMessageConsumer implments both
  javax.jms.QueueReciever and javax.jms.TopicSubscriber interfaces
  that has a common method called receive().  ITCAM tries to get a
  topic when the JMS destination is a queue and vice versa leading
  to the ClassCastException.

Problem summary

• ****************************************************************
  *
  * USERS AFFECTED:
  *
  * Active MQ systems that are embedded within an application
  * server (usually JBoss EAP) monitored by ITCAM for J2EE or
  * ITCAM for WebSphere.
  *
  ****************************************************************
  *
  * PROBLEM DESCRIPTION:
  *
  * The following exception is seen in the ITCAM's
  * trace-dc-bcm.log:
  *
  * <Thread>jmsContainerTracer-1</Thread>
  *  <Exception><![CDATA[java.lang.ClassCastException:
  * org.apache.activemq.artemis.jms.client.ActiveMQQueue cannot be
  * cast to javax.jms.Topic

  * com.ibm.tivoli.itcam.toolkit.ai.callbacks.captureJMS.
  * JMSCallback.beforeSubscriberReceive
  * (JMSCallback.java:2238)
  *
  * This is due to ActiveMQMessageConsumer implments both
  * javax.jms.QueueReciever and javax.jms.TopicSubscriber
  * interfaces that has a common method called receive().
  * ITCAM tries to get a topic when the JMS destination is a
  * lqueue and vice versa leading to the ClassCastException.
  *
  * Though the main user requests that invoke the ActiveMQ is
  * monitored correctly, the nested JMS calls will not be
  * counted correctly due to this error.
