A lot WARING with CSS

[Francisco Javier Godino]

I have an application running perfectly with JAVAFX 2.

I trying to migrate this application to OpenJFX 8.

When I run the program, there is a lot of warning like:

Executing C:\Desarrollos\NovoviaSistema8\dist\run1862230921\NovoviaSistema8.jar using platform C:\Program Files\Java\jdk1.8.0/bin/java
dic 14, 2013 5:11:24 PM javafx.scene.CssStyleHelper lookup
WARNING: caught: 
java.lang.ClassCastException: [Ljavafx.geometry.Insets; cannot be cast to [Ljavafx.scene.layout.CornerRadii;

and the screen look is different. It's not considering my CSS as JAVAFX 2.

Do I need to change somethings?

Thanks
