"exported unconditionally" -- sorry to be picky but this guidance needs 
to be a bit tighter. Can't the user export to a (possibly large) set of 
javaxfx.* modules, rather than unconditionally? Is it OK to _export_ the 
package (rather than open it) because beans will access only its public 
types/members? What if the user opens the package anyway (rather than 
exports it)? I don't know the relationship between the 
PropertyValueFactory type and the type of the items passed to TableView, 
but I think the high-level requirement is: some user type must be 
accessible to JavaFX code, and that is achieved by exporting or opening 
the type's package to at least the javafx.* modules.
