Review Comment:
To be honest, this is a bit of a subtlety. In the early days of flink, there
was a lack of consideration of whether a variable could be null. I have
checked that most of the caller of `TypeInformation#createSerialize` and they
were fine. Unfortunately, there are some exceptions, such as here. 😞
