Error description

  • From MQ Fix Packs 7.5.0.6 and 8.0.0.4 the IBM MQ MFT product has
    been enhanced to support running on AIX when the xlc runtime is
    at version 13.1 or greater.
    
    Previously this combination was unsupported.
    
    At Fix Packs earlier than MQ 7.5.0.6 and 8.0.0.4,  the following
    error is seen in a javacore created after upgrading the AIX
    operating system to include an xlc runtime of version 13.1 or
    greater, and IBM MQ MFT commands fail to execute.
