Default WebView Cookie system not supporting Facebook chat, Gmail Emailing, Google Hangouts etc.

Actually I was trying to create some kind of CookieStore management using the java.net CookieStore and I was able to make them for database but after working few days I found that GMAIL, FACEBOOK are not supported by the WebView in default. I thought it was wrong in my cookie but it seems the problem in more related to default CookieStore used by WebView of javafx.

Some events:
- Try to send email logging with your gmail in standard View.
- Try to chat with your friend online in Facebook.


P.S.
Seems like there is already fix in jdk8 but I would like to know how can I accomplish that from my Custom CookieManager? I made the copy implementation of InMemoryCookieStore and java.net.CookieManager and added these lines

CookieManagerX cmrCookieMan = new CookieManagerX();
CookieHandler.setDefault(cmrCookieMan);

Everything works except those Facebook chat and gmail emailing.

Thanks
