A DESCRIPTION OF THE PROBLEM :
Javafx media player cann' t play online media

REGRESSION : Last worked in version 14.0.2

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
It seems media haven't download or found by mediaplayer,  because local media can play,but online media with http or https can not play.


---------- BEGIN SOURCE ----------
I tested offical code form https://docs.oracle.com/javase/8/javafx/media-tutorial/playercontrol.html
I test it with java 8 and java 14 both. also test with 15-ea+8. 
the result is no error and no media play. Just like it not work, I also search the question in java bug database, found a video hang question maybe similer with this question. https://bugs.java.com/bugdatabase/view_bug.do?bug_id=8242476.
