> When {{Credentials readTokenStorageFile}} gets an IOE. it catches & wraps with the filename, so losing the exception class information.
> Is this needed. or can it pass everything up?
> If it is needed, well, it's a common pattern: wrapping the exception with the path & operation. Maybe it's time to add an IOE version of {{NetworkUtils.wrapException()}} which handles the broader set of IOEs
