在karaf中安装scr特性之后，激活方法被调用了两次

Question

我试图用我已经发布在这个link中的示例来安装apache-karaf 2.3.10的OSGi包。我做了以下步骤

1. Downloaded apache-karaf version 2.3.10 
2. Executed the command features:install scr. Successfully installed scr. I have verified by executing scr:list 
3. Installed all the bundles 
4. Finally after starting all the bundles activate method in ExampleComponentFactoryManager called twice and two objects are created. I have verified the same by executing the command scr:list 
5. After uninstalling the scr feature the activate method in ExampleComponentFactoryManager called only once which is the expected behaviour. 
6. Also i have noted that upto apache-karaf-2.3.10 while installing the scr feature it fetches from the online repo. But from 2.3.11 i am getting error because it tries to fetch it from my maven repository. The error is shown the console. 

有人可以告诉我在卡拉夫特征scr发生了什么？ 因为有了scr功能，我可以看到karaf中有哪些可用的工厂和实例。这是预期的吗？

你可以检查是否有两个运行felix scr软件包的实例。这将解释双重对象的创造。
