      Run this JUnit5 test:

      package com.example;

import org.jboss.weld.junit5.WeldInitiator;
import org.jboss.weld.junit5.WeldSetup;
import org.jboss.weld.junit5.auto.EnableAutoWeld;
import org.junit.jupiter.api.Assertions;
import org.junit.jupiter.api.Test;

import javax.enterprise.context.Dependent;
import javax.enterprise.event.Observes;
import javax.enterprise.inject.spi.AfterBeanDiscovery;
import javax.enterprise.inject.spi.Extension;

@EnableAutoWeld
public class BugHunt5000 {

    @WeldSetup
    WeldInitiator weld = WeldInitiator.from(MyExtension.class).build();

    @Test
    public void dummy () {
        Assertions.assertEquals(42, weld.select(Integer.class).get());
    }
}

class MyExtension implements Extension{

    private void addBean(@Observes AfterBeanDiscovery abd){
        abd.addBean()
           .types(Integer.class)
           .scope(Dependent.class)
           .produceWith(__ -> 42);
    }
}

      A workaround exists: Just add a dummy bean class to the WeldInitiator.

      A Weld SE-Container that has bean discovery disabled, no bean classes, no packages to scan and only extensions, throws an IllegalStateException upon start, because beans.xml is missing:

      WELD-ENV-000016: Missing beans.xml file in META-INFWELD-ENV-000016: Missing beans.xml file in META-INFjava.lang.IllegalStateException: WELD-ENV-000016: Missing beans.xml file in META-INF at org.jboss.weld.environment.se.Weld.initialize(Weld.java:773) at org.jboss.weld.junit.AbstractWeldInitiator.initWeldContainer(AbstractWeldInitiator.java:502) at org.jboss.weld.junit5.WeldInitiator.initWeld(WeldInitiator.java:193) at org.jboss.weld.junit5.WeldJunit5Extension.starWeldContainerIfAppropriate(WeldJunit5Extension.java:272) at org.jboss.weld.junit5.WeldJunit5Extension.beforeEach(WeldJunit5Extension.java:200) at [...]

      This is a problem in situations where I want the only beans to come from the extension(s), for example in a JUnit-test for the extension(s).
