[BGPCEP-772] Example topology not instantiating

Mon, 26 Mar 2018 11:43:36 +0000

Steps to reproduce locally:
(Tried with latest oxygen RC3)
1) start bin/karaf
2) install features>
feature:install odl-restconf
feature:install odl-bgpcep-bgp
feature:install odl-bgpcep-bgp-config-example

And after this I get error in the karaf console>

Exception in thread "Thread-58" java.lang.NullPointerException

These errors are not observed on jenkins tests, however behaviour is similar resulting in script

./get_ipv4_topology.sh

resulting in error> relevant data model does not exist.

It does not happen very often. In dozens of local tests this is observed only few times across several days, and it is not reproducable straight forward.

ADD1: attachement full karaf.log added.
