>             Project: Camel
>          Issue Type: Bug
>          Components: camel-core
>    Affects Versions: 2.12.2
>            Reporter: Stefan Burkard
>            Assignee: Claus Ibsen
>            Priority: Trivial

>             Fix For: 2.12.3, 2.13.0

> A Camel aggregator with persistence repository cannot have a completionSize of 1. If this is configured, every message produces a NPE with the attached stacktrace. 
> I have also attached a small example project that shows the Exception. As soon as the completionSize is > 1, it runs fine.
> This is just a minor flaw, since I cannot think about a really useful case with completionSize 1, but it worked with earlier versions of Camel. 
> As an alternative (if completionSize 1 should not be used), Camel could throw an error during Context startup when completionSize < 2.
