Hi everyone, I finally found the issue. The good news first: The problem is not the camel route and context intialization using blueprint. The Problem was using the hot deploy feature of karaf. I only recieved the exceptions when I overwrote the bundles in the hot deploy folder in order to let karaf load them again. When I removed the bundles from the hot deploy folder first and then copied the new versions of the bundles into the hot deploy folder - everything works just fine. Now the "bad" one: I have absolutely no idea why these Exceptions only occur when I directly overwrite the bundles in the hot deploy feature. So if this is a common flaw of the hot deploy feature in karaf and somebody could explain it to me - I would be very thankful for that. Greetings, Pascal
