Graceful shutdown doesn't work with Karaf camel undertow

Unzip attached reproducer log on Openshift via 'oc login' and create a test project 'oc new-project' Deploy reproducer app mvn clean install && mvn fabric8:deploy Send request on the route with curl http://<your-openshift-route>/rest/srv/count?count=5&cid=42&delay=20000 Which will start the route and delays it for 20sec Wait eg. 10sec, connect via ssh to the container node and kill the docker container with TERM signal with docker kill --signal=TERM <container-id> See that the response from the route was not successful (it should be 948a3163-40c5-4e95-b0c9-69bce8c4667b 6, but I get 502 Bad Gateway HTTP respone)
