Netconf connector dies after another feature with schemas is installed

feature:install odl-netconf-connector-all
then feature:install odl-bgpcep-bgp-all
and after the second feature:install finishes, odl-netconf-connector-all stops working.

Tested on latest Beryllium.
This problem might occur for any feature that deploys additional schemas upon installation in place of "odl-bgpcep-bgp-all" but that was not tested.

In the karaf.log (see attachment) the following suspicious exception happens after the schema change events (there were 2 found).

The NETCONF-144 is related but this is not the case. I added "sleep 60" between the two feature:install commands and also between the ODL startup and the first feature:install command and the behavior persists. The log confirms there are significant time gaps between the feature:install commands and the rest of ODL activity so this is not caused by the second feature:install being executed concurrently with the odl-netconf-connector reconnect. But for odl-bgpcep-bgp-all the odl-netconf-connector reconnect happens twice so I am not entirely sure about this concurrency related argument.
