I'm experiencing problems with playing videos from Youtube on JDK/JRE 8 on Windows 7 x64. I tested it on 3 different notebooks with this OS. On Mac OS there is everything ok and movies always play correctly.
Problem affects "youtube.com" website and Youtube iframe API (HTML5 player). Movies almost always shows error "An error occurred, please try again later" and rarely play correctly.
I've investigated the problem and made simple app with embedded firebug lite and Youtube iframe API that shows the error codes from Youtube player.
Here is Main.java file:

Here is video.html file
https://code.google.com/p/gdata-issues/issues/attachmentText?id=6589&aid=65890000001&name=video.html
To run this just put files in one location, compile and run Main.java
I've posted question on oracle community and there You can see the unexpected output:

Bug reported also on Google tracker, but it is more WebView/Webkit issue:

Unfortunately it is blocking issue in our app and we have not found workaround for this at the moment.
