Improper implementation in GenericUserDAO.selectById ?

[Migrated From Jforum.net]

Hi all, I have written a custom Authenticator class. In that class I want to know if a user with a specific id exists. I do this by calling UserDAO.selectById which is implemented in GenericUserDAO.selectById. However, this method always returns a user object even if no such user exists. The "problem" is this block:

User u = new User();
if (rs.next()) {
   ....
}
return u;

I the GenericUserDAO.selectByName method, the behaviour is different:

User u = null;
if (rs.next()) {
  u = new User();
  .....
}
return u;

Is this how it's supposed to be?
