-------------------------------------
Summary: Updating a configuration may deactivate/active component
multiple times
Key: FELIX-4237
URL: https://issues.apache.org/jira/browse/FELIX-4237
Project: Felix
Issue Type: Bug
Components: Declarative Services (SCR)
Affects Versions: scr-1.6.2
Reporter: Thomas Diesler
* ServiceD has a mandatory unary reference to ServiceD1
* ServiceD1 is backed by a configuration in ConfigurationAdmin (1.6.0)
* Activate the services with no configuration
* Create and update the configuration for ServiceD1
The observed behaviour is
* ServiceD gets deactivated
* ServiceD1 gets deactivated
* New instance of ServiceD1 is constructed and activated with the configuration
* ServiceD1 is bound to to a new instance of ServiceD and ServiceD gets
activated
following this ServiceD1 may get deactivated again causing the above sequence
to get repeated.
In a large dependency graph this would deactivate/activate all components in
the graph. Component activation may not be cheap and should not be done
repeatedly with the same configuration passed in.
