--------------------------------------

Hi [~jark], It is not a case occurred in my online jobs.
I use `TestValuesTableFactory` to create a source table and 
`TestData.fullDataTypesData` as input data which has already contains map with 
null key.
And I defined a sink table which uses json format.
The query is 'Insert into tablesink select * from tableSource'.

For the case  generating the map with null key, I think it may occur in user 
defined functions in reality.
