Hi,
It seems the classpath is not set up correctly.
With Java 11 as my main java, the following works:
java -cp
/usr/share/mediathekview/MediathekView.jar:/usr/share/java/javafx-base-11.jar:/usr/share/java/javafx-controls-11.jar:/usr/share/java/javafx-fxml-11.jar:/usr/share/java/javafx-graphics-11.jar:/usr/share/java/javafx-media-11.jar:/usr/share/java/javafx-swing-11.jar:/usr/share/java/javafx-web-11.jar
mediathek.Main
Since this launches correctly (I haven't tried to load anything though)
it seems the classpath / launch script is the problem.
(If your default java is 8, you may need to set JAVA_HOME or use the
full path name).
