Hi,

This bug is related to the integration with the Nicira Extensions with OpenFlowJava library. I'm using the latest release of Berilium downloaded form the snapshots of the integration project. In summary if you donwload a clean relase and you perform the following installation: "odl-ovsdb-sfc" (with all the dependiences). Everything seems to be fine (no errors in the logs, etc). However, when you "stop" and "start" again and you start to receive packages from OpenStack in the controller you will find this error continuously :

2016-02-02 05:49:45,913 | WARN | entLoopGroup-7-1 | OFDecoder | 172 - org.opendaylight.openflowjava.openflow-protocol-impl - 0.7.0.SNAPSHOT | Message deserialization failed
"java.lang.ClassCastException: org.opendaylight.openflowjava.nx.codec.match.TunIpv4SrcCodec cannot be cast to org.opendaylight.openflowjava.protocol.api.extensibility.HeaderDeserializer"

If seems to be a deserialization exception related to the Nicira "TunIpv4SrcCodec".

Thanks in advance. You are doing an excellent job.

Regards,
Jose
