Felix Meschberger reassigned SLING-42:
--------------------------------------
Assignee: Felix Meschberger
> Potential NullPointerException when initializing Components
> -----------------------------------------------------------
>
> Key: SLING-42
> URL: https://issues.apache.org/jira/browse/SLING-42
> Project: Sling
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.0
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: 2.0.0
>
>
> When a Component is registered with the system, the ComponentResolverFilter
> gets them and if active calls the Component.init method. This may happen at a
> time, that the ComponentRequestHandlerImpl is not registered yet with the
> HttpService and thus the ServletContext is still null. If now the Component
> init method tries to access the ServletContext of the provided
> ComponentContext, a NullPointerException is thrown.
> This whole registration mechanism must be modified such as to only call the
> init methods when the ComponentRequestHandlerImpl is registered with the
> HttpService and has itself been provided with the ServletConfig and
> ServletContext of the servlet container.
> This exception may be seen if the Sling sampl bundle is started before the
> Sling core bundle.
