J.W. Janssen resolved FELIX-4423.
---------------------------------
Resolution: Fixed
Made the stopping of Jetty synchronous with the fix for FELIX-4422, and added
an {{awaitTermination()}} call in the {{stop()}} method. Initial smoke tests
show that the {{ClassCastExceptions}} are gone.

> I sometimes see a class-not-found exception when stopping the OSGi framework
> with a running Jetty bundle. It seems that due to the asynchronous nature of
> this bundle, subtle timing issues can occur during shutdown:
