Description

Using Beryllium-SR1, after installing the OpenFlow plugin using:
feature:install odl-openflowplugin-flow-services-rest

When the first switch connects, I see the following exception:
opendaylight-user@root>Exception in thread "Thread-59" java.net.BindException: Address already in use

and I don't see any of the OpenFlow switches actually connect.

Oddly, if you then shut down the controller (via Control-D) and relaunch it the exception doesn't occur and things seem to work right.

This is when using Mininet 2.1.0.

Colin, I just tried this and could not reproduce in my end. Normally this kind of failures are detected by the test automation, this is why I run to verify myself.
