Toaster throwing an exception when starting with clustering enabled

To reproduce do the following,
1. build the OpenFlowPlugin distribution.
2. Goto the OpenFlowPlugin distribution directory
3. Rename configuration/initial/05-clustering.xml.conf to configuration/initial/05-clustering.xml
4. Run the controller with the following command,
./run.sh -Xmx4G -XX:MaxPermSize=512m

You will see the following exception show up on startup,

My initial thought is that this has something to do with the fact that we substitute the in-memory-datastore with the distributed-data-store using a merge configuration (namely by overriding the settings in 01-md-sal.xml with 05-clustering.xml) which results in the Toaster Modules close being invoked. When the toaster tries it's close it fails with this exception.
