 Quarkus DI solution (also called ArC) is based on the https://jakarta.ee/specifications/cdi/4.0/jakarta-cdi-spec-4.0.html[Jakarta Contexts and Dependency Injection 4.0, window="_blank"] specification.
 It implements the CDI Lite specification, with selected improvements on top, and passes the CDI Lite TCK.
 It does not implement CDI Full.
