Trying to upgrade Meridian 2016 to 2017 received below errors on startup after merging/copying all rpmnew and rpmsave files. install -dis finished okay with no errors. We have 3 node newts/cassandra cluster and postgresql on separate VMs.

I also built a new meridian 2017 VM (vanilla) and just changed opennms.properties to point to newts and openms-datasources.xml to point to database and still get same error.

All virtual machines are CentOS 7.5 (I have not found detailed upgrade notes on 2016 -> 2017 so not sure if im missing something).
