I must be doing something wrong: the player plays `file:` but does not play `jrt:`

plays ok:
FXMediaPlayer source: file:/Users/angorya/Projects/jfx-1/jfx/rt/tests/manual/media/test.mp3

fails:

FXMediaPlayer source: jrt:/Users/angorya/Projects/jfx-1/jfx/rt/tests/manual/media/test.mp3
Exception in thread "JavaFX Application Thread" MediaException: MEDIA_INACCESSIBLE : Users/angorya/Projects/jfx-1/jfx/rt/tests/manual/media/test.mp3 not found

Both jrt:/PATH and jrt:///PATH are failing with the same MEDIA_INACCESSIBLE error,
regardless how I start the player - either in Eclipse or using the `ant + jlink` steps described in FXMedia.jar and launching it with `./dist/FXMediaPlayer/bin/FXMediaPlayer`

Perhaps some steps are missing in the description?
