As per https://errata.devel.redhat.com/rpmdiff/show/178505?result_id=4903242 the RPM contains .sos embedded in JARs. We need to ensure these are either rebuilt from source (as done for the leveldbjni JAR) or stripped.
This is fixed in http://pkgs.devel.redhat.com/cgit/rpms/opendaylight/commit/?h=rhos-12.0-rhel-7&id=fae1e5148bd8f0738401248c0cfa19912bc684b1 and building on https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=14273174
The resulting RPM contains no embedded DSOs and the Karaf container works.
According to our records, this should be resolved by opendaylight-6.2.0-4.el7ost. This build is available now.
Checked with opendaylight-8.0.0-3.el7ost.noarch
In the /opt/opendaylight
