Description
Using getDeclaredMethod of class javafx.scene.media.MediaView with parameters ("setX", double.class) reports an exception:
Caused by: java.lang.ClassNotFoundException: com.sun.media.jfxmediaimpl.platform.ios.IOSMediaPlayer
	at java.net.URLClassLoader.findClass(URLClassLoader.java:385)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:425)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:358)
	... 13 more

Tagging this as regression, as this failure was not present in previous JDK9 versions (e.g., b96 and below).

Please review the following: http://cr.openjdk.java.net/~almatvee/8160988/webrev.00/ Reviewers: kcr, ddehaven Removed dependency on IOSMediaPlayer. Overlay functionality required by IOSMediaPlayer is moved to separate interface and if it is implemented my platform specific media player, then MediaView will provided required information.

This bug was very likely exposed by the reorganization of the build when the Jigsaw m3 changes when in. It looks like there is a hard dependency on the IOSMediaPlayer class from shared code: modules/media/src/main/java/javafx/scene/media/MediaView.java:import com.sun.media.jfxmediaimpl.platform.ios.IOSMediaPlayer; modules/media/src/main/java/javafx/scene/media/MediaView.java: private IOSMediaPlayer getIOSPlayer() { modules/media/src/main/java/javafx/scene/media/MediaView.java: return (IOSMediaPlayer) getMediaPlayer().retrieveJfxPlayer(); This dependency must be removed (e.g., by using reflection and checking at runtime whether the class is available).
