WildFly naming subsystem: how to bind to a java.util.Properties object

Question

I intend to define a JNDI propery of the type java.util.Properties in the WildFly application server to read it from my application.

As described in the an older WildFly documentation one can create a global binding of the type object-factory. In the example is an optional environment tag to hold multiple key/value pairs. That would map exactly my desire to get a java.util.Properties when reading a JNDI resource.

The question is weather there is already an implementiation of javax.naming.spi.ObjectFactory to create a java.util.Properties object out of an object-factory binding or do I need to implement it myself and install it as a separate module (like it is described at mastertheboss.com/...)?
