@ebyhr I've added two more entries

[martint]

Json doesn’t have a concept of maps, so what what’s a null map?

[ebyhr]

cc: @wendigo @chenjian2664

[chenjian2664]

it fixed the issue with reading map columns where the value type is json and the value is null
How about "Fix reading map type when value type is json and value is null"

[ebyhr]

@chenjian2664 Please rephrase to clarify whether it was a failure or a correctness issue. It should start with either "Fix failure when ..." or "Fix incorrect results when …"

[chenjian2664]

Thanks.
It is a failure, so should be "Fix failure when reading map type with value type is json and value is null"
