Summary

0004862: NullPointerException in AbstractCauchoRequest.getUserPrincipal()

Description

NullPointerException in AbstractCauchoRequest.getUserPrincipal()
After looking at the source code which should looks like:

  public Principal getUserPrincipal()
  {
    requestLogin();

    Principal user;
    user = (Principal) getAttribute(AbstractLogin.LOGIN_USER_NAME);

    if (user != null)
      return user;

    WebApp webApp = getWebApp();
    if (webApp == null)
      return null;

    // If the authenticator can find the user, return it.
    Login login = webApp.getLogin();

    if (login != null) {
      user = login.getUserPrincipal(this);

      if (user != null) {
        getResponse().setPrivateCache(true);
      }
      else {
        // server/123h, server/1920
        // distinguishes between setPrivateCache and setPrivateOrResinCache
        // _response.setPrivateOrResinCache(true);
      }
    }

    return user;
  }

Is it possible that the getResponse() return null and cause this?
