I forgot to say that I am working with reflection for getting the class that implements the send method in the third bundle. I tried it now without reflection and it works.
Has anyone experience with the side effects of using reflection in the OSGi environment? Maybe it is a bad idea to use it at all. What I want to achieve is a dynamic environment in which users can add bundles with certain functionality (methods). These methods can be combined with an orchestration language. And for calling a single method I am using reflection as I am only aware of method names and the belonging classes.
