>
> Karaf freezes when a circular dependency is introduced where a features
> references itself over a chain of other features
> I did some experiments with circular dependencies where a feature references
> itself indirectly over some other features. In this case it does not matter
> if attribute {{prerequisite}} is set or not. After command {{feature:install
> c-references-a}} Karaf freezes and must be restarted.
>
> I would expect, that the feature:install command fails with an error message
> like this:
> "Feature com.foo.bar could not be installed because a circular reference:
> a-references-b
> b-references-c
> c-references-a"
> You can checkout a project which helps to reproduce the case from
> [https://github.com/SourcePond/reproduce-feature-circular-dependency.git]
> (Maven-Modules c-references-a and c-references-a-prerequisite-true). Simply
> install the root-project to have all necessary Maven dependencies.
