Given there are also methods to set and get the values of these properties, and the properties themselves are private members, I think it makes sense to wrap these properties in read-only classes when returning them from getter methods.
Examples:
PannableCanvas.scaleProperty
Arrow.startXProperty
Edge.textProperty
In cases where the property should be write-accessible, then the property scope could be public instead of private, though I suppose that does open the member up to reassignment and loss of bindings.
