      Customer is using SelectorAware VTs. They noticed lost messages and have tested it by doing the following:

      Send 100 message to VirtualTopic
      Validate 100 are pushed onto corresponding Queue
      Restart broker - dont start consumer.
      Send 100 message to VirtualTopic again
      At this point, they see the below exception.
      Once they re-attach the consumer, messages flow again.
