> The <config/> element in a feature XML allows a feature to create and/or 
> populate a configuration (identified by a configuration PID).
> The "FeatureConfigInstaller" adds a custom property to the configuration.
> key = "org.apache.karaf.features.configKey"
> value = result of function call "createConfigurationKey(pid[0], pid[1])"
> There are bundles that cannot handle additional properties in the 
> configuration.
> For example:
> * using Aries JPA + Hiberante + h2
> * the configuration is installed by a feature and a realted config entry
> * this will result in a non working setup

> There is a conditional branch in the "findExistingConfiguration" function to 
> filter (find) the configuration using that property instead of the 
> service.pid (this is another conditional branch).
> Is there any reason for using that property?
> I changed the "FeatureConfigInstaller" to not append that property and the 
> above example is working now.
