500 Server error when trying to delete a flow that does not exist

Using latest master branch and odl-openflowplugin-flow-services-ui feature, I do the following:

• Same URL http://127.0.0.1:8181/restconf/config/opendaylight-inventory:nodes/node/openflow:1/table/0/flow/1
• Add a flow - 200 OK
• Remove the flow - 200 OK
• Remove again the flow - 500 Server Error

I get this ugly expection + 500 server error when trying to delete flow that does not exist:
