Review comment:
Right, forgot about that, this is what you was referring to as manual
registration. Ok, here is my suggestion, let us start from this simple solution
(either using `InjectionUtils.STANDARD_CONTEXT_CLASSES`, or in safer with
another collection, f.e. `InjectionUtils.NON_STANDARD_CONTEXT_CLASSES`), and
revisit it later when the PR would be more or less feature complete. I suspect
we are going to have quite a few challenges ahead, so we may use absolutely
different approach at the end :-) At least we could get rid of
`@ContextResolved` for now and move on. Sounds good?

> Revamp of the CXF injection implementation
> -------------------------------------------
>
> Key: CXF-7571
> URL: https://issues.apache.org/jira/browse/CXF-7571
> Project: CXF
> Issue Type: Improvement
> Reporter: Andriy Redko
> Assignee: John D. Ament
>
> As more deep integration with CDI revealed, there are complexities in
> bringing together {{@Context}}- and {{@Inject}}-based injections.
> Encapsulating CXF injection implementation and than delegating the hard work
> to appropriate strategy (CDI, Spring, ...) would be the right solution to
> address the problem at its roots.
