Hi all,

this log:
2014-04-29 16:59:01.751 PDT [nioEventLoopGroup-10-1] ERROR o.o.o.protocol.impl.core.OFEncoder - Serializer for key: msgVersion: 1 msgType: org.opendaylight.yang.gen.v1.urn.opendaylight.openflow.common.action.rev130731.actions.grouping.Action msgType2: org.opendaylight.yang.gen.v1.urn.opendaylight.openflow.common.action.rev130731.DecNwTtl was not found
shows that a message with DecNwTtl action arrived into openflowjava and it is supposed to be serialized into OF 1.0 message. However, there is no DecNwTtl action in OF 1.0. So this message won't leave the controller - openflowjava just throws the exception and discards the message.

Madhusudhan updated the bug with comment that there is difference between data in config and operational datastore, so problem might be there. 

Best regards
Michal Polkorab​

Adding also openflow-java for bug 782 in case they find a clue in the messages:

Hi Abhijit,

Sorry for the confusion, the 2 bugs we are more interested to get fixed is:

- bug 782: it was before datastore but we really want to get these exceptions to disappear from the console

- bug 937: this is the new bug related to new datastore model

Thanks/Luis

Luis, Madhusudhan,

Do you want to assign bug 782 back to Michal? Currently it is under Madhusudhan's name.

Thanks,

Abhijit

Hi all,

These are the two issues we have found so far with the new datastore model:

- OF10 flows not pushed to OVS switch with new OF plugin. Bug 782 to ofplugin project
- Java Exception during controller startup. Bug 936 to controller project

BR/Luis
