This error:

Caused by: java.lang.NoClassDefFoundError: com/sun/javafx/css/parser/CSSParser
at de.jensd.fx.glyphs.GlyphIcon.<clinit>(GlyphIcon.java:48)
at java.base/jdk.internal.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method)

indicates that one of your dependencies (de.jensd.fx.glyphs.GlyphIcon) is trying to access a non existing class (com.sun.javafx.css.parser.CSSParser) in your JDK 9/10.

With the Java 9 release, many JavaFX classes that were private (com.sun.javafx.*) were moved to public API (in this case, javafx.css.parser.CSSParser).

If you run on Java 9 or 10, you have to use third party dependencies at least compatible with Java 9.

From the list of your dependencies:

• ControlsFX

8.40.11 is compatible with Java/JavaFX 8. You need to use ControlsFX 9.0.0

You can download the jar from Maven Central, or add the maven/gradle coordinates:

<dependency>
    <groupId>org.controlsfx</groupId>
    <artifactId>controlsfx</artifactId>
    <version>9.0.0</version>
</dependency>

or:

compile 'org.controlsfx:controlsfx:9.0.0'

• FontAwesomeFX

FontAwesomeFX 8.15 is also compatible with Java/JavaFX 8, so you need to use the 9 versions:

Jars: fontawesomefx-commons, fontawesomefx-controls

or dependencies:

compile 'de.jensd:fontawesomefx-commons:9.1.2'
compile 'de.jensd:fontawesomefx-controls:9.1.2'

others:

compile 'de.jensd:fontawesomefx-emojione:3.1.1-9.1.2'
compile 'de.jensd:fontawesomefx-fontawesome:4.7.0-9.1.2'
compile 'de.jensd:fontawesomefx-icons525:4.2.0-9.1.2'
compile 'de.jensd:fontawesomefx-materialdesignfont:2.0.26-9.1.2'
compile 'de.jensd:fontawesomefx-materialicons:2.2.0-9.1.2'
compile 'de.jensd:fontawesomefx-octicons:4.3.0-9.1.2'
compile 'de.jensd:fontawesomefx-weathericons:2.0.10-9.1.2'

Finally, as posted in comments, the warning is just an indication that your FXML was created with a newer version that the JDK running it. It can be ignored.
