    Description

      In Sender.getExpiredInflightBatches method, delivery.timeout on multiple partitions causes ConcurrentModificationException due to the underlying Java collection being mutated while being iterated on.

      In Java HashMap, you cannot mutate the underlying map while iterating through it, as this will cause ConcurrentModificationException.
