Could you check these? Anyway we need to throw some more useful exception and cookie is not mandatory.</p> <p><a href="https://git.opendaylight.org/gerrit/19685" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/19685</a></p> <p>merged, please retest</p> <p>I also hit the same issue, and i believe it's happening if user don't set the cookie value and cookie value is optional for flow.</p> <p>This bug is related to something that doesn't exist in code base anymore. Please retest and close this bug.</p> <p>looks like the general behavior is now different as well. before, we did not accept a flow mod without a priority. Now, we will take it and assign a default priority of 32768. as long as this is by design, no problem with this bug marked as FIXED. I have an email to openflowplugin-dev asking about this.</p> Blocks OPNFLWPLUG-429 Development External issue ID 3129 External issue URL Rank 0|i03147:
