Problem conclusion

  • The warning message indicates a code path which should be, but
    has not yet been enabled for annotation caching.  The presence
    of the warning message indicates that redundant annotation
    scanning steps are being performed.  The result is a reduction
    of the performance improvements which are provided by annotation
    scanning.  Application function is not impacted: The problem is
    entirely a performance performance and the presence of the
    warning to server logs.
    
    The problem was fixed by a code update which properly enables
    the problem code paths to use annotation caching.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 20.0.0.2.  Please refer to the Recommended Updates page for
