Review comment:
For this part, it's unnecessary to enhance
registerEventDroppedInPrimaryQueue() since it's used for a very small window
(sender is restarting).
I feel your previous solution is good enough.

> When a gateway sender is stopped, events received are stored in a member
> variable of the sender (tmpDroppedEvents) to be later sent to secondary
> gateway senders to remove these dropped events from their queues.
> This events use heap memory from the member and could eventually fill up the
> available memory.
