title: Why is my JSESSIONID now called just SESSION?
body: <p>I have noticed something unusual. Instead usual JSESSIONID for Spring boot 1.3.5/spring security/Embedded tomcat 8</p>
  
  <p><code>JSESSIONID 7B1ADB8E38C5E1CEBD81C4AD88FEEC30 domain.com 42 B/ Session HttpOnly</code> </p>
  
  <p>I am now getting : </p>
  
  <p><code>SESSION    fd0ef173-e17a-440e-8d76-bc63025b3273 domain.com 43 B/ Session HttpOnly</code></p>
  
  <p>Also token looks more lika UUID now. I have tested it, it works but i was just curious why is this happening?</p>
  
  <p>This started happening recently even when i create entirely new project with form login. 
  Maybe i have missed something in spring documentation about it?</p>
