[Java] Generator produces a dedicated field for the discriminator #8137
Description
Origin: https://stackoverflow.com/q/50163882/131929
Is it correct that the generator produces a dedicated field for the discriminator?
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "errorType", visible = true)
@JsonSubTypes({
@JsonSubTypes.Type(value = SpecificError.class, name = "SpecificError"),
})
public class GeneralError {
@JsonProperty("errorType")
private String errorType = null;
...errorType is the declared discriminator.
When Jackson serializes a SpecificError object it includes errorType twice:
{"errorType":"SpecificError","message":"message","errorType":null}
