allowed me to start the hermit Bundle in a Stanbol launcher running trunk.
I have only started the Bundle and have not actually tested the reasoner.
However looking at all the exported packages makes me wonder if they are really
all needed. AFAIK one only exports packages that are directly/indirectly
referenced by the API of the services provided by a bundle. As I am assuming
the the hermit bundle is only implementing a reasoning service I would assume
that it does not need to export any packages.
hope this helps
best
