Error when using mininet

[atomd-zz]

I use 「java -cp build/lib/warp.jar org.flowforwarding.warp.demo.Launcher 」to start controller and I start mininet, and I get a error:

Qualified as a bug, reproduced and started to work on it.

@Dmitry-Orekhov Thank you for your reply.

I am not sure whether warp can only work with LINC Switch? I tried to install openvswitch-2.0.1 to test warp with OF1.3 and also got some errors.
