             Summary: JsonConverter.toConnectData trims BigInteger to Double for schema-less case
                 Key: KAFKA-10457
                 URL: https://issues.apache.org/jira/browse/KAFKA-10457
             Project: Kafka
          Issue Type: Bug
          Components: KafkaConnect
            Reporter: Oleksandr Diachenko
            Assignee: Oleksandr Diachenko
             Fix For: 2.7.0


 

When _JsonConverter_ is configured with _schemas.enable=false_ and value, exceeding _Double_ is passed, the result is incorrect since the converter trims it to _Double:_
{code:java}
Map<String, Boolean> props = Collections.singletonMap("schemas.enable", false);
converter.configure(props, true);
BigInteger value = BigInteger.valueOf(Long.MAX_VALUE).add(new BigInteger("1"));
String msg = value.toString();
SchemaAndValue schemaAndValue = converter.toConnectData(TOPIC, msg.getBytes());
assertNull(schemaAndValue.schema());
assertEquals(value, schemaAndValue.value());
{code}
 

 Fails with:

 
{code:java}
expected:<9223372036854775808> but was:<-9223372036854775808>
Expected :9223372036854775808
Actual :-9223372036854775808
{code}
