> I have an Avro schema resembling the following:
> {code:java}
> {
> "type": "record",
> "name": "StackCalculator",
> "fields": [
> {
> "name": "stack",
> "type": {
> "type": "array",
> "items": [
> "int",
> {
> "type": "record",
> "name": "Dup",
> "fields": []
> },
> {
> "type": "record",
> "name": "Add",
> "fields": []
> }
> ]
> }
> }
> ]
> }
> {code}
> If I create one of these records with the stack:
> {code:java}
> uer::StackCalculator calc;
> uer::StackCalculator::stack_item_t item;
> item.set_int(3);
> calc.stack.push_back(item);
> item.set_Dup(uer::Dup());
> calc.stack.push_back(item);
> item.set_Add(uer::Add());
> calc.stack.push_back(item);
> {code}
> and try to encode this
> {code:java}
> ValidSchema s;
> ifstream ifs("jsonschemas/union_empty_record");
> compileJsonSchema(ifs, s);
> unique_ptr<OutputStream> os = memoryOutputStream();
> EncoderPtr e = validatingEncoder(s, jsonPrettyEncoder());
> e->init(*os);
> avro::encode(*e, calc);
> {code}
> Avro throws {{{}startItem at not an item boundary{}}}. If the records without
> fields are given a dummy field, this works.
> Fix available at [https://github.com/apache/avro/pull/2927] - bot didn't pick
