GridFX on Raspberry Pi & JavaFX 8

For my first JFX demo I tried to create a experimental GridFX version for JavaFX 8. As I mentioned in an earlier post there are some API changed between JavaFX 2 and 8. For GridFX I had to change two things:

– The BaseSkin class is now public

– The CSS support that I used in GridFX seams to work completely different in JavaFX 8.

Both issues were fixed very fast and an GridFX demo was running on my Mac where I have JDK build 1.8.0-ea-b69 installed (download it here). But after deploying the demo on my Pi nothing happened…

So I created a log file for the java output by adding some parameters to the shell command:
java -cp myApp.jar com.guigarage.Demo >log 2>&1
The logging showed me the cause of my problems:
java.lang.NoSuchMethodError: javafx.scene.control.SkinBase.(Ljavafx/scene/control/Control;)V
at com.guigarage.fx.grid.skin.GridViewSkin.(GridViewSkin.java:24)

While everything compiled perfectly on my Mac, the Pi has a different JavaFX compilation / version (build 1.8.0-ea-b36e). As a first solution I downloaded the jfxrt.jar file from my Pi and included it to the GridFX project on my Mac. After doing so I saw all the compilation problems in Eclipse and had a change to resolve them. It would be very nice to have a real 1.8.0-ea-b36 build installed on my Mac. Any idea where to get it?

But after fixing all this problems the GridFX demo is running on my Pi:
