[java] Difference between request.getSession() and request.getSession(true)

They both return the same thing, as noted in the documentation you linked; an HttpSession object.

You can also look at a concrete implementation (e.g. Tomcat) and see what it's actually doing: Request.java class. In this case, basically they both call: 

Session session = doGetSession(true);
