Subject [jira] Created: (FELIX-714) Needless component reactivation on startup

Needless component reactivation on startup

                 Key: FELIX-714
                 URL: https://issues.apache.org/jira/browse/FELIX-714
             Project: Felix
          Issue Type: Bug
    Affects Versions: scr-1.0.4, scr-1.0.2, scr-1.0.0, scr-1.0.6
            Reporter: Felix Meschberger
            Priority: Minor

SCR registers a ManagedService on behalf of each component to receive configuration from the
Configuration Admin Service.

During component activation, SCR executes the following steps:

  * registers a ManagedService on behalf of the Component
  * activates the Component
  * forwards configuration updates to the Component be reactivating it

If on first component activation, the Configuration Admin Service has not yet updated the
ManagedService the component will actually be activated twice: first without configuration
and the second time with the configuration. If the Configuration Admin Service does not actually
have configuration for the Component, the second activation is not needed and should be prevented.
