@ConfigItem Optional<Map<String,String>> does not work

[gastaldi]

Declaring a config as:

/**
 * Sets the placeholders to replace in SQL migration scripts.
 */
@ConfigItem
public Optional<Map<String, String>> placeholders = Optional.empty();

Always returns an Optional.empty() when having the following in the application.properties:

quarkus.flyway.placeholders.foo=bar

I wonder if it is similar to what is not working in OIDC at the moment, where I'd like to have an optional ConfigGroup:

@ConfigGroup
class SomeGroup {}

@ConfigItem
Optional<SomeGroup> someGroup;

(sorry I'll open another issue if it is not related)

[gastaldi]

It may be related. If only I knew where the config is converted/parsed :)

It's probably a different issue @sberyozkin, but even if I'm wrong, it won't hurt to have two open issues for the problem (especially since they're two different symptoms).
