Description

On the first start, if a boot feature contains a <config/> element, and the associated .cfg file exists in the etc folder, then this Configuration can be created twice in ConfigurationAdmin :

1. File Install check the etc folder and create for every cfg a Configuration in ConfigurationAdmin
2. the FeatureService (FeatureConfigInstaller), when a feature is installed and has a configuration, check if this configuration exists in ConfigurationAdmin. If the configuration doesn't exists, then it creates a new one

If 1 and 2 are executed simultaneously, then the same configuration is created twice in ConfigurationAdmin. If this configuration is linked to a managed service, then this service will be instanciated twice.

By default, the karaf-maven-plugin copies every cfg to the etc folder, this issue can probably be triggered by any <config/> element on a boot feature.
