java.lang.NullPointerException: Cannot invoke "java.net.URL.openStream()" because the return value of "java.lang.Class.getResource(String)" is null

Hello,

I just tried to use this library. I took a look at the Demo app and tried to invoke FontAwesomeIconFactory.get() in a similar fashion.
However, this call causes the following exception for me:

java.lang.reflect.InvocationTargetException

    ... 17 more

This is the dependency I included (I had to exclude javafx dependencies, to prevent a conflict with my own dependencies)

<dependency>
    <groupId>de.jensd</groupId>
    <artifactId>fontawesomefx-fontawesome</artifactId>
    <version>4.7.0-11</version>
    <exclusions>
        <exclusion>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-base</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-controls</artifactId>
        </exclusion>
        <exclusion>
            <groupId>org.openjfx</groupId>
            <artifactId>javafx-graphics</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Afaik this is version 11.0, however, I was only able to select 9.0 here.

Kind Regards,
NeunEinser
