    Thrown the HLS completion fails.
    Thrown if an attempt is made to utilise an unknown activity.
    Thrown if an attempt is made to unregister an unknown HLS from the activity.
    The parent activity was invalid in the scope it was intended to be used.
    Thrown if the timeout value associated with the invoking thread which should be applied to newly created activities is invalid.
    Thrown if there is no activity associated with the invoking thread and one needs to be in order to execute the operation.
    The invoking thread does not have permission to attempt to use the operation.
    Thrown if the underlying protocol is violated in some way during termination.
    Marker interface for exceptions e.g.
    Thrown if an error occurs which is not met by another specific exception.
