First question why 2.2.45 is not a released version and it is inside jre7u45 (in the release note) ?

Our application load a FXML andd a new stage on a user action, worked well with older javafx version, now we get this NullPointerException :

What could be the reason (security change during fmxl load?) it doesn't work with 2.2.45 ?

Thank you
