While there is no plan to "open up" more of com.sun.javafx (and that
isn't really the right way to look at it), if you have a proposed
enhancement to the existing public javafx.* classes we could discuss it.
As for your specific example, can you say more about what your use case
is? The GraphicsContext object is a drawing context for a Canvas node,
so it is not a natural place to put an API that computes or returns a
path. I get the sense that you are looking at the existing internal
implementation classes and saying "how can I get access to some
information that might be useful to my application" rather than
describing what your application is trying to do. Once we understand
what you are trying to do, we can discuss whether the need is general
enough to propose adding to the public API of JavaFX and what form such
a new API might take.

I am aware of this and that’s why I am asking. There are useful private
features in com.sun.javafx and I explained one of them in my message. I have
an additional related example but the larger question is if there is a plan to
open more of com.sun.javafx to the public api, documentation surrounding this,
or possibly a complete replacement?
Please consider the example I provided as a feature request.

Is there documentation around the packages (com.sun.javafx vs javafx) used
in JavaFX?
For example, why is there a com.sun.javafx.geom that isn't fully mirrored
in the javafx.scene.shape package? Why are there missing features from
Graphics2D?
I have a specific example that prompted the question:
Consider the following classes:
javafx.scene.shape.Shape
private static Path
createFromGeomShape(com.sunjavafx.geom.Shape geomShape)
javafx.scene.canvas.GraphicsContext
Path2D path;
I want to write a line as follows:
Path path = Path.createFromGeomShape(gc.path);
b/c I want to inexpensively get the outline of the GraphicsContext.
However:
We can't access Path2D b/c it's in com.sun.javafx.geom which isn't exported
by the module.
We can't access Path.createFromGeomShape b/c it's private.
We can't access path in GraphicsContext b/c it's default and doesn't have
an accessor.
A possible solution is to add a new method:
javafx.scene.canvas.GraphicsContext
public Path getPath() {
//implementation copied from
javafx.scene.shape.Shape.createFromGeomShape but use gc.path as the path
}
That would solve my immediate problem but raises the question... why is
com.sun.javafx hidden? What's the architectural reason? Is there any work
in progress that will impact this design?
PS my example is actually very important. I currently use reflection and
module opens in the build to get the path but if the getPath method could
be added to GraphicsContext, that would be great. For performance, it
would be even better to get the PathIterator directly instead of
translating into a javafx..Path but that is related to the bigger question.
