Variable visibility when thread terminates

Could somebody please tell me whether or not the visibility of member variables is guaranteed when a worker thead returns and terminates normally; is a volatile write/read sequence still required in order to guarantee visibility?

After thread t2 detects that thread t1 has terminated, through t1.isAlive() or t1.join(), any writes in t1 is visible to t2. See http://docs.oracle.com/javase/specs/jls/se7/html/jls-17.html#jls-17.4.4
