quarkus.uuid is missing in 2.12.0

[Eng-Fouad]

Describe the bug

ConfigProvider.getConfig().getValue("quarkus.uuid", UUID.class);

This works well in Quarkus 2.11.3. However, it throws an exception in Quarkus 2.12.0:

2022-08-31 17:43:28,918 [] ERROR [io.qua.run.Application] (Quarkus Main Thread) Failed to start application (with profile dev): java.util.NoSuchElementException: SRCFG00014: The config property quarkus.uuid is required but it could not be found in any config source

@radcortez I don't think we have removed it so I suspect a config issue. Feel free to redirect to someone else if it's not.

[gsmet]

And we should probably have a test for that too.

[radcortez]

I was not able to reproduce the issue. I've tried with a sample project with 2.12.0.Final and it worked as expected. I've also added a test in #27634 and it also works.

@Eng-Fouad can you please provide us with a reproducer? Thank you.

Even this simple resource class does not let the server to start normally:

@Path("/uuid")
public class UuidResource {

    @ConfigProperty(name = "quarkus.uuid")
    UUID uuid;

    @GET
    @Produces(MediaType.TEXT_PLAIN)
    public UUID uuid() {
        return uuid;
    }
}

Failed to load config value of type class java.util.UUID for: quarkus.uuid

changing Quarkus version back to 2.11.3.Final makes it working well.

[radcortez]

Caused by #26967.

I also had this bug on some of my apps, let me know if you need another reproducer

[radcortez]

No worries. I was already able to reproduce it. It only happens with RESTEasy Reactive, and I was using RESTEasy Classic. Thanks!

It only happens with RESTEasy Reactive, and I was using RESTEasy Classic

Very interesting... Why the difference?

[radcortez]

We had an issue with DefaultValuesConfigSource. If a namespace was already present it was being overridden if we needed to update it. So what happened was that we write quarkus.uuid with SmallRyeConfigBuilder.withDefault and then mappings will also write their defaults. In this step, the quarkus.uuid was discarded.

This was caused when we added the mapping for RESTEasy Reactive Security: It was because #26967. The issue was already there, just not very visible because you needed a combination of using extension mappings and quarkus.uuid, and we don't have many extensions using mappings yet :)

[geoand]

Gotcha, thanks for the explanation!

[sstefano]

I have the same issue with the latest version of quarkus 2.12.0 + RESTEasy Reactive so, we need to wait for the next release, is it correct?

[gsmet]

We have a 2.12.1.Final planned for tomorrow. I will check if I can backport the SmallRye Config upgrade.
