Bug 155653

Steps to reproduce:

- Create a JavaFX Script file:
-------------------------------------------------------
class TableColumn{
    public var text: String;
}

class TableCell{
    public var text: String;
}

class TableRow{
    public var cells: TableCell[];
}

class SwingTable extends SwingComponent{
}
-------------------------------------------------------

- Fix imports
  The following imports will be added:
-------------------------------------------------------
import javafx.ext.swing.SwingComponent;
import javax.swing.text.TableView.TableCell;
-------------------------------------------------------

Note that 'TableCell' class is defined in the JavaFX file
and this import should not be added.
