Davide Giannella commented on OAK-1730:
---------------------------------------
one more detail. For the integration testing I took the patch from OAK-1717. It
will need to be refactored/cleaned-up as it could share some part with
{{ConcurrentAddNodesClusterIT.java}}. The last to be merged will refactor the
code.
