[jira] [Commented] (QPID-7189) [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
[ https://issues.apache.org/jira/browse/QPID-7189?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15232573#comment-15232573 ]

-------------------------------------------------------
Commit 1738271 from [~k-wall] in branch 'java/trunk'
[ https://svn.apache.org/r1738271 ]
QPID-7189: [Java Client] Consistently name the connection delegates
* The previous inconsistency with the naming of 0-91's delegate was caused by the fact that
AMQP 0-10 implementation misinterpreted 0-91 header.
* Also on the 0-8..0-91 path ensure that a AMQProtocolHeaderException is promptly reported to the caller (rather than causing a hang).

> If broker replies with AMQP 0.9.1 during protocol negotiation, the client is not able to create a delegate as it is looking for delegate using the code 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:
