> If we have a schema where a field is of type RECORD and references an outer-level schema, we get StackOverflowError. For example:
> {
> "name": "person",
> "namespace": "nifi",
> "type": "record",
> "fields": [
> { "name": "name", "type": "string" },
> { "name": "mother", "type": "person" }
> ]
> }
> In this case, if we attempt to add this schema to a HashMap, we get the following error:
