java - JavaFX FXML API version warning

Question

I have recently started noticing the following warning when starting my JavaFX application:

WARNING: Loading FXML document with JavaFX API of version 8.0.65 by JavaFX runtime of version 8.0.60

The FXML in question was created by Gluon Scene Builder 8.1.0, running with it's bundled Java, version 1.8.0_65. The application is launched with my OS Java, version 1.8.0_72.

The root node of the FXML does have the attribute

xmlns="http://javafx.com/javafx/8.0.65"

but I figured 1.8.0_72 > 1.8.0_65, so why am I getting this message? Is it something I should be worried about? And is there a way to ask the jre what is the JavaFX API version (which, apparently, is not the same as the Java version)?

Edit:
Running the code James_D suggested gives the following results:

java version: 1.8.0_72-internal
javafx.version: 8.0.60

So, looks like the JavaFX version in the JDK is wrong? Or maybe I have an old jfxrt.jar? I'll look into that.

If you use the form:

xmlns="http://javafx.com/javafx" xmlns:fx="http://javafx.com/fxml"

The versioning is ignored. You'd only need it if you had some compatibility issue with another version.
