> Key: ARTEMIS-4766
> URL: https://issues.apache.org/jira/browse/ARTEMIS-4766
> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Components: Configuration
> Affects Versions: 2.33.0
> Reporter: Gary Tully
> Assignee: Gary Tully
> Priority: Major
> Fix For: 2.34.0
>
>
> On our extension points, where configuration provides the implementation
> class name, like plugins or transformers, we need to create an instance of
> the configured class at runtime.
> We typically know the interface type we are expecting, so we can enforce this
> check before we create in instance, in that way we won't every call static
> initialises on the wrong type in error. In cases where some gadget can be
> injected into our configuration, it will need to be specialised for our
> interfaces to be effective, which creates one additional hurdle to jump over.
