    @rmetzger Thanks for looking at it.
    
    > Is there a reason why the DataSet methods for "sum()" for example do not allow to
aggregate on POJOs with this change?
    
    The reason is just that i didn't have time to do it. But I think it could be done in a
few hours. I'll open a JIRA.

> The {{PojoFieldAccessor}} (which is used by {{.sum(String)}} and similar methods) doesn't
support nested POJOs right now.
> As part of FLINK-3697 I'll add a check for a nested POJO and fail with an exception.
