/**
    @short      reset all internal structures
    @descr      If someone recycles this instance, he can switch from one
                using mode to another one. But then we have to reset all currently
                used information. Otherwhise we mix it and they can make trouble.

                But note: that does not set defaults for internal used members, which
                does not relate to any job property! e.g. the reference to the global
                uno service manager. Such information is used for internal processes only
                and are necessary for our work.
