Antoine Sabot-Durand Do you have "implicit scan" enabled? AFAIK this functionlity should be disabled by default (due to potential performance problems). In Weld, you could either use org.jboss.weld.se.scan.classpath.entries (as described in http://docs.jboss.org/weld/reference/latest/en-US/html/environments.html#_implicit_bean_archive_support_2) or javax.enterprise.inject.scan.implicit (as described in https://docs.jboss.org/cdi/spec/2.0.EDR2/cdi-spec.html#bean_archive_se) to enabled this functionality.
