I'm trying to create a styleable property of type CornerRadii, which requires a StyleConverter to create the CssMetaData. It would be great if the StyleablePropertyFactory provided support for CornerRadii in the same way as for Paint, Insets, etc., but because it doesn't a custom solution is required. An internet search yielded Oracle API 'CornerRadiiConverter' that looks like exactly what I need. The only problem is that it doesn't exist in the JDK I'm using (JDK 10.0.2]. Interesting, since the converter specified in the link is supposed to be reside in the package javafx.scene.layout, which is not restricted API.
Does this converter still exist, and if so where can I find it, and if not is it ever coming back, and if so then what is a good ETA?
