--------------------------------

             Summary: NullPointerException at org.apache.aries.subsystem.core.internal.WovenClassListener.modified
at org.apache.aries.subsystem.core.internal.RegionUpdater.addRequirements
                 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


An 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.
