org.fxmisc.flowless.CellListManager#getCellIfPresent

changes the implementation as blow is better.

public Optional<C> getCellIfPresent(int itemIndex) {
    if (itemIndex>=cells.size()||itemIndex<0){
        return Optional.empty();
    }
    return cells.getIfMemoized(itemIndex); // getIfMemoized() may throw
}
