Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of:
  
  - The MQ V9 AMQP channel
  
  who have MQ Light or Qpid-JMS client applications that:
  
  - Use SASL authentication when connecting to a queue manager
  using an instance of the AMQP channel.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The new version of the Qpid-JMS client (version 0.20.0) changed
  how SASL data was being flown. The new SASL flows were not
  understood by the IBM AMQP channel, because SASL data was
  expected to arrive with a certain order. Due to this, the
  Qpid-JMS clients were not able to be authorized with the queue
  manager and received the following error:
  
       MQRC 2035 MQRC_NOT_AUTHORIZED [condition =
  amqp:unauthorized-access]
  

Problem conclusion

• The IBM AMQP channel has been updated so that it is can handle
  the new SASL flow and successfully authorize the Qpid-JMS client
  with the queue manager.
