Hank.X.Hua created AMQ-4622:
-------------------------------

             Summary: Broter connect to themselves when using the Multicast Transport in NetworkConnector
                 Key: AMQ-4622
                 URL: https://issues.apache.org/jira/browse/AMQ-4622
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker, Connector, JMS client, Message Store
    Affects Versions: 5.8.0
         Environment: pc(computer), windows 7(os),Multicast Transport,networkConnector
            Reporter: Hank.X.Hua
             Fix For: 5.x


ActiveMQ Configuration´╝Ü
<broker useJmx="true" xmlns="http://activemq.apache.org/schema/core" brokerName="Hank1"
dataDirectory="${activemq.data}">
    <transportConnectors>
           <transportConnector name="openwire" uri="tcp://0.0.0.0:61623?maximumConnections=1000&amp;wireformat.maxFrameSize=104857600"

		discoveryUri="multicast://239.254.254.254:6255?group=mq"/>
    </transportConnectors>
    <networkConnectors>
	<networkConnector name="MQ1" uri="multicast://239.254.254.254:6255?group=mq"/>
    </networkConnectors>

With this configuration, after starting the MQ, the MQ will appear " Network connection between
vm://Hank1#0 and tcp://Computer name/IP:61623@50576(Hank1) has been established" in the activemq.log,
When a consumer is listening, it will appear two consumer in "Number of Consumer" of  "http://localhost:8168/admin/queues.jsp".This
will lead to not receive the complete message(for example producer send 100 messages, the
consumer of "ID:WCMIS147-50871-1373073323074-0:1" will receive 73 messages,and another one
of "TalendESB-MQ1_Hank1_inbound_Hank1
" will receive 27 messages)

So ,I think this bug is dangerous,if it was really exsit
