@tomas-langer looks to me (I don't know this area at all) like Helidon's HOCON support is not allowing customization of the ConfigFactory options that would permit this use case:

https://github.com/oracle/helidon/blob/b3fd9c0d19b1d8a2fc090a8c212cb7b2179d1407/config/hocon/src/main/java/io/helidon/config/hocon/HoconConfigParser.java#L129

We're using this:

https://github.com/lightbend/config/blob/v1.4.1/config/src/main/java/com/typesafe/config/ConfigFactory.java#L739-L741

…and the default options do not include a ConfigIncluder:

https://github.com/lightbend/config/blob/v1.4.1/config/src/main/java/com/typesafe/config/ConfigParseOptions.java#L47-L49

Do you concur?
