Exception for long field when value can be represented with a integer

[JeremieBergeron]

When specifying a value for a field of type "long" that falls within the 32-bit integer range (like 2147483647), the generator raises an exception because it appears to expect values that don’t overlap with the 32-bit integer representation. Oddly, values that exceed the 32-bit integer range (such as 2147483648) work as expected, suggesting an issue with how values are parsed or type-checked within the generator.

Exception Details

The generator throws the following exception when specifying 2147483647:

Exception in thread "main" java.lang.RuntimeException: Invalid option for record schema: type org.apache.avro.generic.GenericData$Record, value '{"a": "exemple", "b": 2147483647}'

In contrast, values outside the 32-bit integer range, like 2147483648, do not trigger this error.

Example JSON Schema

Here’s the schema that causes the exception:

{
    "namespace": "datagen.example",
    "name": "users",
    "type": "record",
    "fields": [
        {
            "name": "a",
            "type": "string"
        },
        {
            "name": "b",
            "type": "long"
        }
    ],
    "arg.properties": {
        "options": [
            {
                "a": "exemple",
                "b": 2147483647
            }
        ]
    }
}

However, if we use 2147483648 for "b", it works correctly.
