If one runs the Fish app with the network disconnected one gets

     [java] Exception in Application start method
     [java] MediaException: UNKNOWN : com.sun.media.jfxmedia.MediaException: could not connect to media (http://reavers.us.oracle.com/fish/water-splash-2.aiff) : com.sun.media.jfxmedia.MediaException: could not connect to media (http://reavers.us.oracle.com/fish/water-splash-2.aiff)
     [java] at javafx.scene.media.AudioClip.<init>(AudioClip.java:59)

Ideally the exception type should be MEDIA_INACCESSIBLE.
