GWT GIN-琐碎的用例失败（EventBus）

GIN模块：

public class InjectorModule extends AbstractGinModule {
    @Override
    protected void configure() {
        bind(EventBus.class).to(SimpleEventBus.class).in(Singleton.class);
    }
}

注射器：

@GinModules(InjectorModule.class)
public interface Injector extends Ginjector {
    EventBus getEventBus();
}

GWT模块入口点：

public class Module1 implements EntryPoint {
    private final Injector injector = GWT.create(Injector.class);

    public void onModuleLoad() {        
        injector.getEventBus();
    }   
}

删除通话即可injector.getEventBus()使一切正常。呼叫injector.getEventBus()原因：

Caused by: java.lang.RuntimeException: Deferred binding failed for 'com.google.web.bindery.event.shared.EventBus' (did you forget to inherit a required module?)

GWT开发模式说：
