/** @short      implements a listener, which will update the
                global filter cache of an office, after zje office
                startup was finished.

    @descr      To perform startup of an office, the filter cache starts
                with a minimum set of properties only. After the first document
                was loaded successfully a thread will be started to fill the
                cache with all other proeprties, so it can work with the whole
                filter configuration.
