    can't say anthing about illegal or not - but subclassing the
    ui-delegates always is a pain, usually involving c&p of lots of private
    methods which are changing between versions.

    There's another approach: make sure the list is doesn't grow beyond the
    area that's filled with items (return false on
    getScrollableTracksViewportHeight), make sure the viewport has the same
    background color as the list and register a mouselistener with the
    viewport that clears the selection on pressed.
