Aljoscha Krettek commented on FLINK-1962:
-----------------------------------------
Sorry, your comment did not appear yet when I wrote my reply.
My fix should work this time. Even though it looks quite ugly because of the
dual casting. The reason for this is that the TupleTypeInfo constructor has
type bounds on T to only allow subclasses of Tuple. The T I have in the
TypeInformationGen method does not have these type bounds, so I have to cast
things around, but the end result should be correct this time.
I'm sorry this look so long. I've never looked at the graph API in depth before.
