This was resolved almost a year ago, but the JBS bug was never updated. http://hg.openjdk.java.net/openjfx/9-dev/rt/rev/3962c15cd0dc changeset: 9376:3962c15cd0dc user: Morris Meyer <morris.meyer@oracle.com> date: Wed Nov 11 17:14:27 2015 -0500 summary: 8142439: Ensemble8 media player slider issues

Morris, I don't want you to spend any more time on these minor issues since the sample works okay, but still here's my thoughts: I think that isValueChanging is meant to be used for sliders which should take action only after the user releases the thumb but still track the value change. So since we are reacting to value change immediately I don't think there is any need to use this call. Actually, updateValues is called anyway after the call of mp.seek() through the mp.currentTimeProperty() listener. And it will call setValue on timeSlider again, duh! BTW, there is an empty volumeSlider InvalidationListener at the line 305. Anyway, sine the sample works correctly, that's a +1

That is the correct assessment of the changes.

It appears that the only substantive changes are: 1) Switched to using a change listener rather than an invalidation listener for timeSlider.valueProperty() 2) Added an else block in the above listener looking for a large enough change in value to seek to the appropriate place without calling updateValues(). 3) Removes a couple redundant if tests where the body of the "if" and "else" blocks were identical Did I miss anything? It looks fine to me, so I'll defer to Vadim in case he has something else in mind.
