> {code:java}
>     private Long getEndOffset(List<Long> offsets) {
>         if (offsets == null || offsets.isEmpty()) {
>             return null;
>         }
>         return offsets.size() > 1 ? offsets.remove(0) : offsets.get(0);
>     }
> {code}
> The above code has two issues.
> 1. It does not return the latest offset since the latest offset is at the end of offsets
> 1. It removes the element from offsets so MockConsumer#endOffsets gets non-idempotent
