I am compiling line.fx from JavaFX Tutorial lesson 1 which from
http://inkspb.russia.sun.com/FXDocs/Concepts/Franca/ui/overview/line.fx

Got compilation errors:
C:\>javafx-sdk1.1\bin\javafxc line.fx
.\Color.fx:3: Color is already defined in this compilation unit
import javafx.scene.paint.Color;
^
line.fx:10: cannot find symbol
symbol : variable DARKSLATEGRAY
location: class Color
def stroke = Color.DARKSLATEGRAY;
                  ^
line.fx:17: cannot find symbol
symbol : variable LINEN
location: class Color
            fill: Color.LINEN;
                       ^
3 errors

The code needs to be added the import:
import javafx.scene.paint.Color;

After added the import, the code is running fine.
Attached is modified code.
