LinearGradient doesn't appear in JavaFX mobile application

Question

Hi everyone.
I'm developing a JavaFX mobile application. The scenes will have a Gradient of black and green background color.
Here is the code.
var scene1 : Scene = Scene{
        fill: LinearGradient {
        startX: 0.0, startY: 0.0, endX: 0.0, endY: 1.0
        proportional: true
        stops: [ Stop { offset: 0.0 color: Color.BLACK },
                 Stop { offset: 1.0 color: Color.GREEN } ]
        contentAccording to JavaFX API, LinearGradient is found in common profile. Which means I should be able to use it in my mobile application. But when deploying it into an actual mobile phone, the scene's background is plain white.
Why doesn't it take effect??
When running the application into a mobile emulator, it is just fine.

I think there was a bug in LinearGradient + proportional. Is it using latest JavaFX runtime on phone?
Just to confirm this, can you specify absolute coordinates (with proportional: false) for LinearGradient?
I faced this issue long time back while implementing background of InterestingPhotos, but now it works fine.
