RestApiException (and any subclass of it) is caught and rethrown as a RestApiException with a generic message. This causes the actual exception type and message to be lost. Don't catch RestApiException; allow the original to propagate. Also add tests in ChangeIT to verify behavior when rebasing with and without the rebase permission.
