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.
