I forgot to mention once again: I don't expect any errors if you are using Java 8.

The first error of the type:
Canvas3D: GraphicsConfiguration is not compatible with Canvas3D
or the second error about the null GraphicsConfiguration, are both acceptable.

Both errors messages can be created by crafting the convenient code and both of these messages are useless.

Eventually, the getBestConfiguration(based_on_this_3D_template) method is called and eventually, you can create 3D objects despite any previous error messages.

But you cannot call this method in Java 9.
