Hi All.

When using version 999-SNAPSHOT, I get this error when trying to get all the property names of the Injected Config Object from MicroProfile Config:

I recreated the issue using the quarkus-quickstarts. I just added the following to GreetingResource.java in the getting-started project:

@GET
    @Path("/config")
    @Produces(MediaType.APPLICATION_JSON)
    public Response config() {
        JsonArrayBuilder arrayBuilder = Json.createArrayBuilder();
        for(String property:config.getPropertyNames()){
            String value = config.getValue(property, String.class);
            arrayBuilder.add(Json.createObjectBuilder().add(property, value).build());
        }
        return Response.ok(arrayBuilder.build()).build();
    }

see:
https://github.com/phillip-kruger/quarkus-quickstarts/blob/master/getting-started/src/main/java/org/acme/quickstart/GreetingResource.java

This works fine with 0.12.0, so it's something that is indroduces recently.

Please let me know if you need more details.
