>    Affects Versions: 1.10.0
>            Reporter: Iván Ezequiel Rodriguez
>            Assignee: Iván Ezequiel Rodriguez
>            Priority: Major

> It is related to the bug I reported a few days ago +*NIFI-6800*+
> This is another problem in the StandardProcessSession.java, promptly in the combination of the counters for the event repository-> flowFileEvent object.
> The putALL method is called and the values ​​are not being mixed when it comes to existing keys
>  As we know hashmap does not allow duplicate keys. So when we merge the maps in this way, for duplicate keys in map1 the value is overwitten by value for same key in map2.
> *_The putAll method cannot be used to combine hashmasp if what is expected is that the keys be summed_*.
