StackOverflowError for Connect WorkerTask

[Vladoiu Catalin]

Hi guys,

I am trying to use Confluent Platform 3.3.0 and the S3-Connector and I get
a StackOverflowError error:

java.lang.StackOverflowError

at io.confluent.connect.avro.AvroData.toConnectSchema(AvroData.java:1381)
at io.confluent.connect.avro.AvroData.toConnectSchema(AvroData.java:1359)

with the following schema structure:

@namespace ("com.test.avro")
protocol TestError {
  record TestError {
    union { null, string } type = null;
    union { null, array<TestError> } errors = null;
  }
}

I wrote a basic unit test for AvroData.toConnectSchema(...) and that one is
also failing with the same error:

@Test
public void testToConnectDateAvroCustomEanError() {
  org.apache.avro.Schema avroSchema = new
org.apache.avro.Schema.Parser().parse("{\"type\":\"record\",\"name\":\"TestError\",\"namespace\":\"com.test.avro\",\"fields\":[{\"name\":\"type\",\"type\":[\"null\",{\"type\":\"string\",\"avro.java.string\":\"String\"}],\"default\":null},{\"name\":\"errors\",\"type\":[\"null\",{\"type\":\"array\",\"items\":\"TestError\"}],\"default\":null}]}");
  avroData.toConnectData(avroSchema, 10000);
}



Is this a known issue, or I am doing something wrong?

Thanks,
Catalin
