I've looked at the code in the past. Basically when advertising a service, it tries to create a proxy for use by the Aries Quiesce stuff but seems to fail randomly on certain interfaces. On failure, it bails and just returns the original object (hence the message "Returning the original object instead"). It's a bug in the Aries proxy lib. </p> <p>If it doesn't happen in karaf 4 then it's been fixed.</p> <p>&gt; this occurs in Karaf 3, so it's not a Karaf 4 issue.<br/> &gt; If it doesn't happen in karaf 4 then it's been fixed.</p> <p>I can hereby confirm that this problem does not occur in the logs of Karaf 4 distributions (e.g. in netvirt/vpnservice/distribution/karaf/target/assembly built with <a href="https://git.opendaylight.org/gerrit/#/c/55160/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/55160/</a>), whereas it still is seen on Karaf 3.</p> <p>With the current plan of switching completely to Karaf 4 (only) during Nitrogen, I therefore suggest that we close this as RESOLVED WONTFIX at this point, because it soon won't occur anymore on future Nitrogen distributions (once we're all on Karaf 4, which as of right now we're not). Should plans change unexpectedly, then we can always re-open this.</p> <p>&gt; does not occur in the logs of Karaf 4 distributions</p> <p>or does it?! <a href="https://jira.opendaylight.org/browse/SFC-196" title="Karaf4 exceptions in SFC distribution" class="issue-link" data-issue-key="SFC-196"><del>SFC-196</del></a> claims it still does in SFC on k4...
