注入ng2的ng1 $ rootScope依赖项在aot中出现问题（ng1 - ＆gt; ng2 hybrid）

Question

我已经创建了以下RootScope的$ rootScope包装器，之后我在angular2服务下使用了这个，例如xService。

import {Injectable, Inject} from "@angular/core";

@Injectable()
export class RootScopeService {
    static instance: RootScopeService;
    public $rootScope: any
    // constructor( @Inject("$rootScope") public $rootScope: any) 
    constructor() {
        return RootScopeService.instance = RootScopeService.instance || this;
    }
    public broadcast(eventName, event, scope) {
    this.$rootScope.$broadcast(eventName, event, scope);
    };
    public getRootScope(): any {
        return RootScopeService.instance.$rootScope;
    };
}

import {Injectable, Inject} from '@angular/core'
import {Logger, Level} from 'angular2-logger/core'

@Injectable()
export class xService {
    private log: Logger;
    private static instance: xService;
    constructor( @Inject("$rootScope") public rootScopeService: any) {
        if (xService.instance == null) {
            this.log = new Logger();
            this.log.Level = Level.DEBUG;
            xService.instance = this;
        }
        return xService.instance;
    }
    trackCustomEvent(customEvent, currentScope) {
        try {
            xService.instance.rootScopeService.broadcast(customEvent, currentScope);
        } catch (ex) {
            x.instance.log.error("x:: trackCustomEvent : " + ex.toString());
        }
    }
    trackActionEvent(actionEvent, scope) {
        xService.instance.trackCustomEvent(actionEvent, scope);
    }
}

我已经使用AOT编译并且编译时没有失败。然后使用汇总创建构建文件。运行build.js文件时 获得以下问题
