Jetty Exceptions on bundle shutdown of Fuse

Issue

We have jetty consumer endpoints (proxies) configured on different ports in different bundles. However on shutdown of one of the bundles, we always get "Failed to shutdown Jetty server on port " warnings. How do we fix them? Even on startup there are exceptions on jetty mbean
