this is the right thing to do:
UsernamePasswordToken token = new UsernamePasswordToken(name,password);this makes a mistake:
UsernamePasswordToken token = new UsernamePasswordToken(name, password, subject.isRemembered());or this may also report an error:
UsernamePasswordToken token = new UsernamePasswordToken(name, password, rememberMe);
