The sal-rest-docgen bundle is being stopped and multiple stacktraces are printed to logs.<br/> I’ve tested it using my dummy feature which is dependent on nothing and I was able to reproduce it also with odl-jolokia feature.<br/> Installation of bundles works well, I have these troubles with features only.<br/> I was able to reproduce this issue by karaf4 distribution of lispflowmapping project as well.<br/> Piece of logs attached.</p> <p>Operating System: All<br/> Platform: All</p> NETCONF-412

Feature operations at Karaf4 trigger stop of restconf bundles
