Type problem in RichFlatMapFunction when using GenericArray type

[Martin Junghanns]

Hi,

I ran into a problem when using generic arrays in a tuple. I wrote a 
minimal program to reproduce the error [1].

The problem seems to be related to the order of tuple fields. When
I switch Tuple2<K[], K> to Tuple2<K, K[]> and perform the join on field 
0, everything works as expected.

Using Flink 1.1.2.

Cheers,
Martin
