Xander Uiterlinden commented on FELIX-2816:
-------------------------------------------
This is most likely caused by overlapping init methods. One for the servlet
init and one for the component lifecycle callback method. It can be resolved by
specifying another name for the init callback for the component lifecycle by
using the Component.setCallbacks method.
> dependency manager calls init() twice

> Key: FELIX-2816
> URL: https://issues.apache.org/jira/browse/FELIX-2816
> Project: Felix
> Issue Type: Bug
> Components: Dependency Manager
> Reporter: Derek Baum
>
> Log messages are placed at the beginning of the component lifecycle methods
> (init, start, stop, destroy).
> The number is the hashCode, which shows that init() is called twice on the
> same Object, without intervening stop() or destroy():
> [Debug] [ ] MyServlet 1397120162 init: update=60
> [Debug] [ ] MyServlet 1397120162 start: endpoint=/myservlet period=60
> history=null
> [Debug] [ ] MyServlet 1397120162 init: update=60
> [Debug] [ ] MyServlet add: gx2
> [Debug] [ ] MyServlet add: denzil
> The component is created as follows:
> manager.add(createComponent()
> .setImplementation(MyServlet.class)
> .add(createConfigurationDependency()
> .setPropagate(true)
> .setPid(PID))
> .add(createServiceDependency()
>
> .setService(HttpService.class).setRequired(true))
> .add(createServiceDependency()
> .setService(UserAdmin.class).setRequired(true))
> .add(createServiceDependency()
>
> .setService(MyStateStore.class).setRequired(false)
> .setCallbacks("addStore",
> "removeStore"))
> .add(createServiceDependency()
>
> .setService(HistoryService.class).setRequired(false))
> .add(createServiceDependency()
>
> .setService(LogService.class).setRequired(false))
> );
