Because you configure the switch not to send any data in a packetin
message. That's why you hit the previous Ryu bug.
Check miss_send_len config:
fujita@ubuntu:~$ sudo ovs-ofctl show br0
OFPT_FEATURES_REPLY (OF1.2) (xid=0x2): dpid:0000060387abae49

OFPT_GET_CONFIG_REPLY (OF1.2) (xid=0x4): frags=normal miss_send_len=0
