Rafael H. Schloming commented on QPID-1344:
-------------------------------------------

My clever cloning plot didn't quite work because Throwable doesn't permit you 
to overwrite the initial cause once it is set, however I submitted something 
that is reasonably equivalent.

> low level refactoring for replay breaks protocol negotiation

> Summary:
> The change in QPID-1339 is causing Protocol negotiation to fail.
> Problem
> The initial problem is that the check for protocol 0-10 in ClientDelegate was 
> incorrect preventing the ProtocolVersionException from being propogated to 
> the connection.
> The new Connection class also wraps the  ProtocolVersionException so 
> AMQConnection is unable to work out the new protocol to try so it continues 
> to try 0-10 until failover is exhausted.
