AbstractMCServerBase now does (once it is working properly I will move the extra code to LifecycleEventListeners)


   @Override
 
   protected void doInitialize() throws IllegalStateException, InvalidConfigurationException, LifecycleEventException
 
   {
      // NEW CODE - 1
      /*

       * Make sure we have the correct classpools set up  

       */
 
      //Initialize jboss-reflect to use the correct classpools
 
      JBossClClassPoolConfig config = JBossClClassPoolConfig.getInstance();
 
      RepositoryClassPoolFactory factory = new RepositoryClassPoolFactory(config.getClassPoolRepository());
 
      JavassistTypeInfoFactoryImpl.setPoolFactory(factory);
      // NEW CODE - 1 - END
 
 
 
      /*

       * We need to start the bootstrap here so we can set the kernel

       * before we fire start kernel events 

       */
 
      this.initializeBootstrap();
 
 
 
      // Call Super implementation
 
      super.doInitialize();
 
 
 
      // NEW CODE - 2
 
 
      //Install the bean configuring the classpools
 
      BeanMetaDataBuilder builder = BeanMetaDataBuilder.createBuilder("JBossClClassPoolConfig", JBossClClassPoolConfig.class.getName());
 
      builder.setFactoryClass(JBossClClassPoolConfig.class.getName());
 
      builder.setFactoryMethod("getInstance");
 
      ValueMetaData inject = builder.createContextualInject(null, null, AutowireType.BY_NAME, InjectOption.CALLBACK);
 
      //TODO add name to BeanMetaDataBuilder
 
      ((AbstractInjectionValueMetaData)inject).setValue("ClassLoading");
 
      builder.addPropertyMetaData("classLoading", inject);
 
 
 
      try
 
      {
 
         getKernel().getController().install(builder.getBeanMetaData());
 
      }
 
      catch (Throwable e)
 
      {
 
         // AutoGenerated
 
         throw new RuntimeException(e);
 
      }
 
      // NEW CODE - 2 - END
 
 
 
 
   }
 
 
 

The stuff in 1) sets up the classloader system so it understands the bootstrap classloaders
The stuff in 2) "listens" for ClassLoading and registers the container as a module Handler
