With the recent tightening of the restrictions on the use of setAccessible done as part of JDK-8169069, we need to update the FXML spec to indicate that applications in a named module that wish to use @FXML to annotate non-public methods or fields must explicitly allow such access by declaring this in their module-info.java file. The applications must "opens" the package(s) in question to javafx.fxml or an IllegalAccessException will be thrown.
