Try Probe - look into the internals

Probe development tool allows to inspect the application CDI components at runtime. See also the demo application hosted on OpenShift.

java -Dorg.jboss.weld.development=true -cp 'target/cdi-beyond-ee-0.0.1-SNAPSHOT.jar:weld-vertx-probe.jar' com.githhub.mkouba.cdibee.vertx.HelloApp
