/**
* This class uses a custom classloader, and general trickery to load the JFX tools JAR from the JAVA_HOME for the
* Maven execution. It assumes the JAVA_HOME is set to a valid JDK installation with JavaFX installed within it.
*
* This would not be necessary if the JavaFX tools JAR file was available in a public repository. Currently however
* there are legal restrictions against non-Oracle developers redistributing any official JavaFX code. This reflection
* based solution avoids this by using the officially distributed tools JAR that comes with the JDK.
