in errai 4.2.2 there is no method getInstance() in the IOCBeanDef interface,

but it is used in the documentation.

public MyManagedBean { 
  @Inject SyncBeanManager manager;  
  public void lookupBean() { 
    IOCBeanDef<SimpleBean> bean = manager.lookupBean(SimpleBean.class);  
    if (bean != null) { 
      // get the instance of the bean 
      SimpleBean inst = bean.getInstance(); 
    } 
  } 
}

So how to get an instance of the bean.

kindly regards.
