TCK: Jakarta CDI 4.1 Lite

This page consolidates the state of the official CDI 4.1 TCK runs against Vauban. The source of truth is the vauban-tck-runner, executed on every build: 774/774 CDI Lite tests pass (100%).

Category Reason

Category	Reason
Runtime portable extensions (`Extension`, `BeforeBeanDiscovery`, `AfterBeanDiscovery`)	Out of the Lite profile. Vauban implements only Build Compatible Extensions.
`@ConversationScoped`	Out of the Lite profile.
`PassivationCapable` / passivation	Out of the Lite profile. Beans are not serialisable.
EL wired into managed beans	Out of the Lite profile. `jakarta.el` is required only as a spec dependency, not activated on application beans.
`@Specializes`	Out of the Lite profile (deferred to a possible Full profile).

Runtime portable extensions (Extension, BeforeBeanDiscovery, AfterBeanDiscovery)

Out of the Lite profile. Vauban implements only Build Compatible Extensions.

@ConversationScoped

Out of the Lite profile.

PassivationCapable / passivation

Out of the Lite profile. Beans are not serialisable.

EL wired into managed beans

Out of the Lite profile. jakarta.el is required only as a spec dependency, not activated on application beans.

@Specializes

Out of the Lite profile (deferred to a possible Full profile).

Tests skipped for environment reasons

Arquillian tests requiring a servlet container: out of scope for Vauban (covered by Foy).
Advanced EL tests: require an application-level EL evaluator, not wired in the Vauban runner.

VAU-PRX-002

Reproduce locally

cd vauban
sdk env
mvn install -DskipTests -q && mvn test -pl vauban-tck-runner -Ptck

The runner uses Arquillian + TestNG. The Surefire report lands in vauban-tck-runner/target/surefire-reports/.

Per the workspace constraint, vauban-tck-runner is included in the Vauban reactor — unlike cassini-tck or foy-tck, which are detached because of ShrinkWrap Maven Resolver. The CDI TCK does not depend on ShrinkWrap Resolver in this configuration.
