> Key: ARIES-1429
> URL: https://issues.apache.org/jira/browse/ARIES-1429
> Project: Aries
> Issue Type: Bug
> Components: Subsystem
> Affects Versions: subsystem-2.0.4
> Reporter: John Ross
> Assignee: John Ross
> Fix For: subsystem-2.0.6
>
>
> A NullPointerException [1] may occur while updating a region as part of
> adding dynamic imports to the sharing policy for a bundle containing a woven
> class. This will only occur when something outside of the subsystems
> implementation for whatever reason has deleted the region digraph edge that
> connects the parent subsystem to the subsystem containing the bundle whose
> class is being woven as a constituent.
> Still, it would be useful if the implementation would allow this by replacing
> the NPE with a noop. In other words, if the implementation does not find an
> existing edge between parent and child, it would simply assume that something
> else is handling the dynamic imports.
