The following error seems to happen when config file is pushed, but only for features in featuresBoot, not when feature:install is issued at runtime.

2016-03-16 04:48:42,313 | ERROR | config-pusher | ConfigPusherImpl | 108 - org.opendaylight.controller.config-persister-impl - 0.4.1.Beryllium-SR1 | Failed to apply configuration snapshot: 00-netty.xml(odl-mdsal-broker,odl-mdsal-broker)

Also, this error does not happen on Beryllium snapshot builds. Attached TRACE logs when odl-config-netty is the feature present in featuresBoot.
