I left one comment inline about an unused variable that can be removed. There are also leftover `SuppressedWarnings` annotations that can be removed from both files.

@jayathirthrao Can you be the second reviewer?

modules/javafx.swt/src/main/java/javafx/embed/swt/FXCanvas.java line 359:

I think `FXCANVAS_PERMISSION` is unused after this and can be removed (along with the related import).
