--------------------------------

             Summary: [Java Client 0-8..0-10] Client fails to create delegate for AMQP 0.9.1
in response to broker supported protocol recieved during protocol negotiation
                 Key: QPID-7189
                 URL: https://issues.apache.org/jira/browse/QPID-7189
             Project: Qpid
          Issue Type: Bug
          Components: Java Client
    Affects Versions: qpid-java-6.0.1, qpid-java-6.0, 0.32
            Reporter: Alex Rudyy


If broker replies with AMQP 0.9.1 during protocol negotiation, the client is not able to create
a delegate as it looks for delegate using the below:
{code}
String delegateClassName = String.format("org.apache.qpid.client.AMQConnectionDelegate_s_%s",
 pe.getMajorVersion(), pe.getMinorVersion());
{code} 

There is no delegate AMQConnectionDelegate_0_91

The client fails with exception as below:
{noformat}
Exception in thread "main" javax.jms.JMSException: Error creating connection: Protocol: 0.91
is rquired by the broker but is not currently supported by this client library implementation
