             Summary: [Java Client] Connection establishment can send invalid frame sequence when retrying
                 Key: QPID-6179
                 URL: https://issues.apache.org/jira/browse/QPID-6179
             Project: Qpid
          Issue Type: Bug
            Reporter: Rob Godfrey
            Assignee: Rob Godfrey


Occasionally one sees erroneous protocol traces such as illustrated by the following:

{noformat}
[apache.qpid.client.AMQConnectionDelegate_8_0] Connecting to broker:tcp://localhost:10002?connectdelay='500'&retries='0'
[transport.network.io.IoNetworkTransport] SO_RCVBUF : 65535
[transport.network.io.IoNetworkTransport] SO_SNDBUF : 65535
[transport.network.io.IoNetworkTransport] TCP_NODELAY : true
[qpid.client.state.StateWaiter] New StateWaiter :AMQState: id = 4 name: CONNECTION_OPEN:[AMQState: id = 4 name: CONNECTION_OPEN, AMQState: id = 6 name: CONNECTION_CLOSED]
[qpid.protocol] SEND: [org.apache.qpid.client.protocol.AMQProtocolHandler@501fdcfb] AMQP1109
[apache.qpid.client.AMQConnection] Connection 3 now connected from /127.0.0.1:50631 to localhost/127.0.0.1:10002
[apache.qpid.client.AMQConnection] Are we connected:true
[apache.qpid.client.AMQConnection] Connected with ProtocolHandler Version:0-9
[apache.qpid.client.AMQConnectionDelegate_8_0] Write channel open frame for channel id 
                                                     ^^^^^^^^^^^^
# What on earth

The issue stems from a prior connection attempt which has reached the connection open stage, but then (for some reason) closed.

We can rectify this issue by using a new StateManager for each connection attempt.
