Deadlock on loading Binding Serializer

We are observing an issue on controller restart where modification operations (put/merge) on transactions get deadlocked on looking for a serializer.

Here is the link to the threads that are locked up.

pool-55-thread-1 is BLOCKED on getting the Serializer.
pendaylight-cluster-data-akka.actor.default-dispatcher-3 is WAITING for the generation of a Serializer to complete.

It appears that the generating of the serializer is not completing and thus the deadlock.
