Disable cookies in Java Web Start

I was creating application for Java Web Start that works with URLConnection. At some point, I have noticed strange behavior: for same requests I was receiving different responses. Digging deeper, I found that it was sending cookies that I was creating in browser by regular site browsing.

This became interesting and I googled it and found interesting document. So using browser cookies is actually a feature and was intentionally done and worked in Java Web Start and Java Plug-in applications.

For my case it was totally undesirable and I wanted to turn it off. Fortunately, it can be done quite easily (though more complicated then it should be):

       CookieManager cookieManager = new CookieManager();
       CookieHandler.setDefault(cookieManager);
       cookieManager.setCookiePolicy( CookiePolicy.ACCEPT_NONE);
