It is required in my project to load the system library "jfxrt.jar" classes into my project. groupId: com.oracle artifactId: javafx version: 8.0

Yes, this jar defines its own `javafx.beans.value.ObservableValue`, and may be it is a wrapper of this class which is inside "jfxrt.jar" which is existing inside the JDK. Yes the problem...
