             Summary: MQTT Transport can generate class cast exception when subscription is to a Virtual Topic
                 Key: AMQ-5298
                 URL: https://issues.apache.org/jira/browse/AMQ-5298
             Project: ActiveMQ
          Issue Type: Bug

    Affects Versions: 5.10.0
            Reporter: Timothy Bish
             Fix For: 5.11.0


When a client subscribes to a Virtual Topic and sends a duplicate subscription request the method that resends the old retained messages tries to cast the destination from the TopicRegion is finds to a Topic but in this case it would be a VirtualTopicIntercepter and an exception is thrown disconnecting the client.
