    ****************************************************************
    When first connecting to a data grid or after restarting a
    data grid while leaving the client running, a client does meta
    data recovery for the COPY_TO_BYTES function.  When doing this
    recovery, a reply from the server is sent with the updated meta
    data information.  This interaction with the
    server was not taken into consideration when determining
    whether a retry should occur when fail fast is enabled
    (requestRetryTimeout=0).  This APAR allows for an additional
    interaction with the server when doing this recovery logic and
    not does not allow failing fast for this special response type.
