Running a simple Media/MediaPlayer test program to play mp3 file from disc.

Runs like charm on Java FX runtime version: 2.2.45-b18/jdk1.7.0.45

Changing in Netbeans (7.4) Platform from JDK 7 to JDK 8: Java FX runtime version: 8.0.0-b128

the following exception is thrown:

As the MediaPlayer instantiation with JFX 2.2 works fine, I assume all required Linux libraries are present.

Debugger in JFX code does not give any hint.


                        String fileUrl = theStreamPath.toUri().toString();
                        Logger.getLogger("").log(
                                Level.INFO,
                                "playIndefiniteStream: Read file: {0}",
                                new Object[]{fileUrl});
                        final MediaPlayer mediaPlayer = new MediaPlayer(new Media(fileUrl));
                        mediaPlayer.setOnError(new Runnable() {
                            @Override public void run() {
                                Logger.getLogger("").log(
                                        Level.SEVERE,
                                        "playIndefiniteStream: Media Player Error: {0}",
                                        new Object[]{mediaPlayer.getError()});
                            }
                        });
                        mediaPlayer.setAutoPlay(true);
