Jetty unable to find its SSL keystore in Fabric registry: FileNotFoundException: /opt/fuse/jboss-fuse-6.3/profile:fuse.jks (No such file or directory)

Issue

When securing the Jetty based HTTP server in Fabric by following Enabling SSL/TLS for Jetty in a Fabric and placing the SSL keystore into the Fabric registry (not on file system!) then the container may raise the following error at start-up. As a result the web console may not be accessible (it loads an empty page in the browser).
