A code > comment would be helpful since it is non-obvious. Instead of negation, it should have been at the opposite positions. I have fixed this in the latest commit. The arg list order for [`concatenate`](https://github.com/openjdk/jfx/blob/a56ba63bef9b33c4ad5cc9e05ae5bdb0ee480a3f/modules/javafx.graphics/src/main/java/com/sun/javafx/geom/transform/AffineBase.java#L2849) is different compared to the constructor of Affine2D. ------------- PR: https://git.openjdk.java.net/jfx/pull/190
