> Key: ISIS-834
> URL: https://issues.apache.org/jira/browse/ISIS-834
> Project: Isis
> Issue Type: Improvement
> Components: Core
> Affects Versions: core-1.5.0
> Reporter: Dan Haywood
> Priority: Minor
> Fix For: 1.16.1
>
>
> Two complications:
> - ExceptionRecognizers require multiple implementations (are chained together)
> - for each implementation we identify all the types it implements, so the check isn't a simple 1:1 map (at the limit all implementations extend java.lang.Object). Therefore need to take into account the set of injection points that the services are injected into.
