Felix Meschberger resolved FELIX-4792.
--------------------------------------
Resolution: Fixed
Implemented catching any Throwable during initial component initialization and
logging it in Rev. 1658457.
In addition the component is disabled to make sure any partical setup is rolled
back.
> [SCR] Handle Errors on component initialization
> -----------------------------------------------
>
> Key: FELIX-4792
> URL: https://issues.apache.org/jira/browse/FELIX-4792
> Project: Felix
> Issue Type: Bug
> Components: Declarative Services (SCR)
> Affects Versions: scr-1.8.2
> Reporter: Felix Meschberger
> Assignee: Felix Meschberger
> Fix For: scr-2.0.0
>
>
> During component initialization the component implementation class is loaded.
> If the class or one of its dependencies cannot be properly loaded a
> ClassDefNotFound error can be thrown.
> This error bubbles up from BundleComponentActivator.initialEnable to the
> AbstractExtender.createExtension method, where it is logged. The problem with
> this is, that the BundleComponentActivator has registered all the components
> of the bundle with the ComponentRegistry but when the error is thrown, the
> BundleComponentActivator is not registered in Activator's m_componentBundles
> map.
> So, when the bundle is stopped, the components registered with the
> ComponentRegistry stay registered and will never be cleaned away.
> The simple fix is to catch Throwable in the
> BundleComponentActivator.initialEnable method and log it. The single
> component failing to load will stay inactive but the rest of the component
> registration will continue unaffected.
> Background: We have a situation where a bundle is compiled against an API
> bundle whose exported API is not properly versioned. So the OSGi framework
> happily wires the bundle to the older API bundle version but one of the
> components fails to load due to missing API.
