> When a factory pid adapter is losing one of its required service dependencies, it is stopped, but when the lost dependency comes up again, the configuration adapter instance is not re-created and re-started.
> Example:
>  * A factory configuration adapter has a required dependency on a "Required" service.
>  * The factory configuration is created, the "Required" service is registered, so a factory configuration adapter INSTANCE1 is then created.
>  * Now the "Required" service is unregistered: the INSTANCE1 is then stopped.
>  * And when the "Required" service comes up again, then a new factory config adapter INSTANCE2 should be re-created, updated and started, But since R1 this is not the case anymore.
> The bug is located in the AbstractDecorator.stop() method, this method currently does this:
> {code}
>     public void stop() {
>         for (Component component : m_services.values()) {
>             m_manager.remove(component);
>         }
>     }    
> {code}
> Clearly, this is a bug because the "m_services" list is not cleared, so when the AbstractDecorator.updated(String, Dictionary) method is called again, it finds again some old stale components, and updates them instead of re-creating new adapter instances.
> In DM3, the list was correctly cleared:
> {code}
>     public void stop() { 
>         Object[] components;
>         synchronized (m_services) {
>             components = m_services.values().toArray();
>             m_services.clear();
>         }
>         for (int i = 0; i < components.length; i++) {
>             m_manager.remove((Component) components[i]);
>         }
>     }    
> {code}
> I will add a test case soon.
