Config mapping beans not available in a custom Hibernate ConstraintValidator

[ivansenic]

Describe the bug

Having a config mapping class:

@ConfigMapping(prefix = "some.props")
public interface MyConfig {
}

I can not inject it into a custom ConstraintValidator using:

@ApplicationScoped
public class MyValidation implements ConstraintValidator<..., ...> {

    @Inject
    MyConfig config;

Exception being thrown:

Caused by: java.util.NoSuchElementException: SRCFG00027: Could not find a mapping for ....MyConfig
	at io.smallrye.config.ConfigMappings.getConfigMapping(ConfigMappings.java:111)
	at io.smallrye.config.SmallRyeConfig.getConfigMapping(SmallRyeConfig.java:411)
	at io.quarkus.arc.runtime.ConfigMappingCreator.create(ConfigMappingCreator.java:31)

Expected behavior

Config mappings can be injected, as they can be injected to other ApplicationScope beans.

Actual behavior

No response

Build tool (ie. output of mvnw --version or gradlew --version)

Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63) Maven home: /home/ise/.m2/wrapper/dists/apache-maven-3.8.6-bin/67568434/apache-maven-3.8.6 Java version: 17.0.6, vendor: Private Build, runtime: /usr/lib/jvm/java-17-openjdk-amd64 Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "5.15.0-69-generic", arch: "amd64", family: "unix"

Additional information

Workaround is to use the @ConfigProperty(name = "..") in the validator, which works atm.

Duplicated by #24540.

Please use Instance<MyConfig> to inject the mapping.

Closing in favor of #24540.
