      Description

      The following exception is thrown during container initialization:

      It happens that the following call in org.jboss.weld.bean.proxy returns a negative hashcode:

      if (bean != null) {
          final BeanIdentifier id = Container.instance(contextId).services().get(ContextualStore.class).putIfAbsent(bean);
          name.append(Math.abs(id.hashCode()));
      }
      

      That leads to with an invalid class name.
