Hi I would suggest paxexam-karaf.

Date: Tue, Jun 26, 2012 9:25 am Hi Achim, thanks for the insight. Guess I'll go down the route you suggested, at least until I find some time at my hand to do some more experimentation. Regards Jerry p.s. The classloading issue you describe below could stem from the fact that one bundle gets passed an object that implements an interface from one bundle, but resolves the interface definition from another bundle, maybe even itself. Maybe you could try setting a breakpoint at the code location and compare the classloaders?
