MicroProfile Config supports automatic converters.

This is an essential feature required for MicroServices using java.net.URI/java.net.URL. This works because they own a public constructor accepting a single String like new URL(String).

Basic types like String, Numbers, and Booleans are currently supported in JBoss Tools. But using an injection like this:

@Inject
@ConfigProperty(name = "service.location")
URI serviceLocation;

will result in a warning

No bean is eligible for injection to the injection point [JSR-365 §5.2.2]
