Thanks Robert,
i don’t manage to run the build with the proposed option. However, i’ve moved
some suspected class out of the interface, only in the implementation, and get
the same error, but happening a bit further, basically in the component
implementing the interface [0]. I guess i’m next to it :-) but still can’t find
that. I’m using clapper for class information browsing through 2 dependencies
[1], the incriminated class is org.clapper.util.classutil.ClassInfo. Those
dependencies required me to add the maven.clapper.org repository within the
project.
