`SmartLoginModule.java` is a class used by a test, itself is not one since there's no `main()` method.

Your new test needs to be a regression test, which means before the fix it fails and after the fix it succeeds. Also, seeing the exception message in a jtreg output with your own eyes is not a test. The test itself should detect the exception and decide whether it's a success or a failure. In the case, I'd recommend you use the `System.setErr` method to store the output into a `ByteArrayOutputStream` and then look into it.
