      I'm not shouting *BUG* since it works in 6.0M3 and it *is* a SNAPSHOT, I'm merely tracking down what has changed.

      Looking at the source it comes from

          public static void notifySessionStartup(HttpSession session) {
              SessionDispatcher sessionDispatcher = lookupSessionDispatcher(session.getServletContext());
              try {
                  sessionDispatcher.checkSession(session);
              } catch (Exception e) {
                  throw new RuntimeException(e);
              }
          }

      where the sessionDispatcher is null, I don't see how getting the attr from the SessionContext could fail so how could it fail setting it?
