Yes, this is intentional. This entry is dedicated solely to `Password`, and it is expected that `System.console()` will be called beforehand so that normal cases (without redirection) are handled by `System.console()`. The null check is a safeguard to prevent future `Password` refactoring from invoking this method without first calling `System.console()` in the standard case.
