Local fix

• N/A
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of the IBM MQ v9.0.0 Managed File
  Transfer (MFT) embedded agent component included within IBM
  Integration Bus (IIB).
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The IBM MQ v9.0.0 Managed File Transfer (MFT) embedded agent
  running within an IBM Integration Bus (IIB) execution group
  could not be restarted due to a java.lang.NullPointerException
  that was thrown when generating a list of MQ component
  information to be written to the event log of an agent.  This
  was because the product code that operated on the list of found
  MQ components expected at least one component to be found and
  did not expect a null value.
  

Problem conclusion

• The IBM MQ Managed File Transfer (MFT) class used to write
  information to the agent's event log has been changed to handle
  the case when no MQ component information could be found, thus
  avoiding a java.lang.NullPointerException from being thrown.
  
  ---------------------------------------------------------------
  The fix is targeted for delivery in the following PTFs:
  
  Version    Maintenance Level
  v9.0 CD    9.0.5
