Review comment:
ok. I will remove it.
Anyway, if the gateway sender is created with manualStart=true then the
eventProcessor will not be yet instantiated. In that case, and until the
gateway sender is started we could see dropped events put in tmpDroppedEvents.
It cannot be guaranteed that it will be a small time window.

> 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.
