sometimes making producer class @dependent scoped make work. i'm not sure. , in case, have "bean-discovery-mode=all" doesn't make differents.
but in case, have mistake in imports.
your producer produces "import org.jboss.logging.logger;" , injected field java.util.logging.logger . don't have appropiated producer de type class wanted inject.
