As we talked yesterday - thanks for investigating this and finding the issue. Let's hope that will help us support OVS 2.4.

The current implementation of openflowjava refuses to keep the connection to switches which implements unsupported features. As a result, if a supported switch implements a new feature, it could become unsupported until the controller implements the codec (serializer/deserializer) to this new feature. However, it could just ignore any unsupported feature and use only the supported ones.

This is happening today for Open vSwitch 2.4. There are some features which are not yet supported by the controller and it is keeping people from using it.

To fix that, I have submitted a patch to ignore unsupported features on table features:

Feedback is appreciated.
