> With Jackrabbit, the following API call
> {code}
> UserManager#getAuthorizable(String auth)
> {code}
> with either {{null}} or {{""}} used to throw
> {code}
> throw new IllegalArgumentException("Invalid authorizable name '" + id + "'");
> {code}
> With Oak UserManager, the same input does not throw an IAE, but instead return a {{null}} value when providing {{""}} and throws a NPE when providing {{null}}.
> From my POV, it would be best to avoid throwing exceptions on those two cases. Indeed, returning a {{null}} value is simpler for the API user and would comply with the API.
> If so, the implementation in case of {{null}} may be changed in order to swallow the {{null}} value and the difference between Jackrabbit and Oak may be documented.
