    *                      copied tree was causing data            *

    * RECOMMENDATION:                                              *
    ****************************************************************
    During materializing a copied node, a notification was being
    sent to the copies of the node to unnecessarily materialize
    themselves. This extra operation was causing data corruption in
    the copied nodes. This can cause an
    ArrayIndexOutOfBoundsException in the
    FastAccessMediator.getInternalFastAccess method.
    

Problem conclusion

  • The materializing algorithm was updated to avoid materializing
    nodes (elements, attributes and namespaces) when it is not
    needed by disabling the mechanism for sending notification to
    the copied node during materializing.
    
    The fix for this APAR is currently targeted for inclusion in
    fix packs 8.0.0.12 and 8.5.5.7.  Please refer to the
