[OPNFLWPLUG-701] NullPointerException in FlowRemovedTranslator

Mon, 27 Sep 2021 09:01:49 +0000

Version:
master (db2760aa10bad041a6357b4af855b0a48bb1ea48)

Steps to reproduce:

1. Start controller and OF10 switch.
2. Disable statistics manager.

POST /restconf/operations/statistics-manager-control:change-statistics-work-mode
Body: {"input": {"mode": FULLY_DISABLED}}

3. Install a flow entry into OF10 switch with specifying timeout and SEND_FLOW_REM flag.

POST /restconf/operations/sal-flow:add-flow
Body:
{
"input": {
"node": "/opendaylight-inventory:nodes/opendaylight-inventory:node[opendaylight-inventory:id=\"openflow:1\"]",
"table_id": 0,
"idle-timeout": 10,
"hard-timeout": 0,
"priority": 10,
"match": {
"ethernet-match": { "ethernet-type":

{ "type": 2048 }

},
"ip-match":

{ "ip-protocol": 1 }

,
"icmpv4-match":

{ "icmpv4-type": 8, "icmpv4-code": 0 }

},
"flags": "SEND_FLOW_REM"
}
}

4. Wait for the OF10 switch to send FLOW_REMOVED message.

NPE is caused when FLOW_REMOVED message is received.
