      Description

      A new serailizer object is created to handle on each conversion from Openwire to STOMP. The serializer uses heavy reflection resulting a lot of GC and CPU utilization. This is un necessary and not scalable. One serilaizer could be created for each subscription and reutilize that for the subscription.
