@JsonSubTypes does not work as a field annotation

[vtyro]

Expected Behavior

JSON Serialization/Deserialization of @JsonSubTypes with @SerdeImport for implementation class and generic field should work correctly.

Actual Behaviour

When I use @JsonSubTypes for interface or abstract class and use @SerdeImport for implementation class, than deserializer throw error:
Error decoding JSON stream for type [interFace]: Unable to deserialize type [InterFace]: No default constructor exists io.micronaut.http.codec.CodecException: Error decoding JSON stream for type [interFace]: Unable to deserialize type [InterFace]: No default constructor exists at app//io.micronaut.json.codec.MapperMediaTypeCodec.decode(MapperMediaTypeCodec.java:170) at app//io.micronaut.http.codec.MediaTypeCodec.decode(MediaTypeCodec.java:143) at app//io.micronaut.http.codec.MediaTypeCodec.decode(MediaTypeCodec.java:210) at app//com.example.JacksonSerdeTest.testSerdeImportDeserializeErr1(JacksonSerdeTest.java:43)
It's ok if I using @Serdeable annotation. Another problem with Deserialize when using generic field: data is lost.

Steps To Reproduce

I create simple example in gitlab.

I think this is a Micronaut Serialization not a Micronaut Problem JSON issue right?

There is one remaining issue here, we don't support type info annotations on properties like here: https://github.com/vtyro/jackson-serde/blob/master/src/main/java/com/example/err4/Model4.java

I will rename this issue and mark it as improvement, though the #634 was a bug.
