Java Maps and Type Information

[Simone Robutti]

Hello,

to my knowledge is not possible to use a java.util.Map for example in a
FlatMapFunction<java.util.Map, java.util.Map>. Is that correct? It gives a
typer error at runtime and it doesn't work even with explicit
TypeInformation hints.

Is there any way to make it work?

Thanks,

Simone
