Typesafe config load from java.util.prefs.Preferences

I'm trying to figure out how to properly instantiate a Config instance using a java.util.prefs.Preferences object.

The API exposes a ConfigFactory.load() method that takes a java.util.Properties parameter, but for the life of me I can't figure out how to do the Preferences to Properties conversion.

Do you guys have any hints?

P.S. I get the preferences object as a parameter from an external context and modifying it to something more convenient is not really an option.

There seems to be no direct way to do it. Implementing ConfigParseable to add new kinds of file formats/APIs is very explicitly not supported.

The easiest thing I can think is to write your own method for converting Preferences to Properties recursively, using childrenNames() and keys().
