---------------------------------------
Yes I think it would work but I like to cover the DM plumbing under the hoods.
I added a simple example to the description to cover what I'm after.
> Support for static field injections and callback invocations

> Key: FELIX-3912
> URL: https://issues.apache.org/jira/browse/FELIX-3912
> Project: Felix
> Issue Type: Improvement
> Components: Dependency Manager
> Reporter: Tuomas Kiviaho
>
> I've got a case (JUnit tests) where static field injections and callback
> invocation would be more than welcome. I'm succesfully using
> DependencyManager in the same manner as Sonatype Sisu for my integration
> tests, but test execution times become quite high when using @TestRule
> instead of @ClassRule.
> The codebase seems to be crafted statics in mind since there are only handful
> of locations which prevent this. The biggest blocker is
> Component.setImplementation that would need an information preventing
> instantiation. The same information would be used to determine at callbacks
> and field injections whether to perform these or not.
> I guess that the most pain would come from annotation api where possibility
> of method overloading should be taken into account, but that could get static
> support later on.
> I could provide a patch if this idea gets wind under it. Personally I dislike
> the idea of using statics anywhere else that within unit/integration tests.
