Is map_struct_to_json thread safe?

[byrnexu]

The following code sometimes gets the first half of json, I suspect it is because of the result of calling in a multi-threaded environment, the following fieldinfo is a local variable

struct_mapping::map_struct_to_json(fieldInfo, oss, " ");

No, struct_mapping is not thread safe. But perhaps that's not the point. It would be nice to see a more detailed code example.
