John Ross resolved ARIES-738.
-----------------------------
Resolution: Fixed
Changed the for:each loop into a for loop using an Iterator. The
Iterator.remove method is then used to remove candidates when necessary.
> [subsystems] The subsystem resolver hook modifies a collection it's iterating
> over.

> Project: Aries
> Issue Type: Bug
> Components: Subsystem
> Reporter: John Ross
> Assignee: John Ross
>
> The SubsystemResolverHook is used to prevent the resolution of content
> bundles within an isolated subsystem. Within the filterResolvable method, it
> modifies the candidate collection (candidates.remove) while iterating via a
> for:each loop which causes a ConcurrentModificationException.
