> Comparison of GenericData in the java avro library is incorrectly implemented.
>  
> Two bugs exists:
> 1) Shortcut returning of 'different' is wrong, since it compares m1.size() != m1.size() instead of m1.size() != m2.size()
>  
> 2) When one of both maps are empty, the iterator throws an exception. There is no 'isEmpty' check.
>  
> See PR: [https://github.com/apache/avro/pull/2325]
