IT30768: Managed transfers fail with a BFGBR0119E message, where the BFGBR0119E messagestops after the word "because".

APAR status

• Closed as program error.

Error description

• An MQ Managed File Transfer protocol bridge agent (PBA) connects
  to a file server using the SFTP protocol and acts as the
  destination agent for a managed transfer. Occasionally, managed
  transfers involving the agent fail and the managed transfer
  includes the following supplementary information:
  
  BFGBR0119E: Bridge agent was unable to create directory
  <directory name> because
  
  The BFGBR0119E message stops after the word "because", and does
  not contain any information about why the managed transfer
  failed.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  This issue affects users of MQ Managed File Transfer, who have
  protocol bridge agents that:
  
  - Connect to file servers using the SFTP protocol.
  - And act as the destination agent for managed transfers.
  - And process managed transfer requests that require a new
  directory to be created on the file server.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  MQ Managed File Transfer protocol bridge agents (PBA) use the
  third-party JSch library to communicate with file servers using
  the SFTP protocol. If an issue occurs that prevents JSch from
  being able to perform the requested SFTP operation, it throws an
  exception back to the PBA. The PBA will catch that exception,
  and handle it appropriately.
  
  If the exception indicates an issue has occured which prevents
  the managed transfer from being completed, then the PBA will
  mark the managed transfer as "Failed". The PBA will also
  generate a supplementary message providing more details about
  the failure, using information contained within the exception
  thrown by JSch.
  
  Now, if a PBA:
  
  - Was acting as the destination agent for a managed transfer.
  - And received a managed transfer request that required it to
  create a new directory on the file server.
  - And the JSch library was unable to create that directory due
  to a permissions issue.
  
  then the exception thrown by JSch would not always contain an
  additional information. In this situation, the supplementary
  message generated by the PBA looked like this:
  
  BFGTR0072E:  The transfer failed to complete due to the
  exception: BFGBR0119E: Bridge agent was unable to create
  directory <directory name> because
  
  The message stopped after the word "because" which made it
  appear incomplete, when in fact there was no additional
  information for the PBA to include.
  

Problem conclusion

• To resolve this issue, MQ Managed File Transfer protocol bridge
  agents (PBA) have been updated so that:
  
  - If they are acting as the destination agent for a managed
  transfer.
  - And they are processing a managed transfer request that
  requires a new directory to be created on the file server.
  - And the JSch library is unable to create that directory.
  - And the exception thrown back by JSch does not contain any
  information about why the directory could not be created.
  
  then the PBA will mark the managed transfer as "Failed" with the
  following supplementary message:
  
  BFGTR0072E:  The transfer failed to complete due to the
  exception: BFGBR0209E: Bridge agent was unable to create
  directory <directory name>
