>          Components: Declarative Services (SCR)
>    Affects Versions: scr-1.2.0

> This issue is related to the following dev post: -> http://www.mail-archive.com/dev@felix.apache.org/msg14167.html
> There are two components that comes into play: 
> 1) The first one (EnglishDictionary) has a configuration-policy="require" parameter and a factory="true" parameter:
> <?xml version='1.0' encoding='utf-8'?>
> <component name='EnglishDictionary' xmlns='http://www.osgi.org/xmlns/scr/v1.1.0' factory='true' configuration-policy='require' modified='updated'>
>  <implementation class='com.alcatel_lucent.samples.scr.dictionary.english.EnglishDictionary'/>
>  <service>
>    <provide interface='com.alcatel_lucent.samples.scr.dictionary.DictionaryService'/>
>  </service>
> </component> 
> The EnglishDictionary parameter has actually a CM Configuration which is required before activation: that is why it uses configuration-policy='require'.
> 2) The second one (EnglishDictionaryFactory) is a factory component that is meant to instantiate the EnglishDictionary component.:
> <?xml version='1.0' encoding='utf-8'?>
> <component name='EnglishDictionaryFactory'>
>  <implementation class='com.alcatel_lucent.samples.scr.dictionary.english.EnglishDictionaryFactory'/>
>  <reference name='bind' interface='org.osgi.service.component.ComponentFactory' bind='bind' unbind='unbind' target='(component.name=EnglishDictionary)'/>
> </component> 
> The issue takes place when the EnglishDictionaryFactory component tries to instantiate the EnglishDictionary like this:
> class EnglishDictionaryFactory {
>   public void bind(ComponentFactory factory) {
>     factory.newInstance(new Hashtable());
>   } 
> }
> -> The newInstance raises the following exception:
> org.osgi.service.component.ComponentException: Failed activating component
