Bug parsing flow statistics message



I've been trying to get flow statistics from an Open vSwitch using HP's SDN Controller Service function getFlowStats but it seems to have a problem reading the reply from the switch.


I'm creating a flow entry that pushes a Vlan Header, sets the Vlan Id field to 100 and sends packets out a specific port.
I've narrowed it down to realize that the error is cause when the controller reads a flow message that contains a SET_FIELD action.


Using Wireshark I can see the flow entry is correctly installed on the switch and I can even see their messages being exchanged and packets being correctly marked with the Vlan Id.

When the controller receives the of_flow_stats_reply message it shows following log message:


 [2015-06-11 13:39:41.953] WARN of-io-26-thread-14 hp.of.msglib Parse terminated before end. Start=0, Target=192, Read=178, Remaining=14


Wanted to know if someone could help me solve this problem or find an alternative solution.


Thank you,

Pa Martins
