Records with polymorphic types sent from native clients received with no data

[galderz]

Describe the bug

Sending records that include polymorphic types from a native Quarkus app using rest-client to a jvm Quarkus app contains empty data.

The data model uses com.fasterxml.jackson.annotation.JsonSubTypes and com.fasterxml.jackson.annotation.JsonTypeInfo to handle polymorphism, and the types in the reproducer look like this:

public record MammalFamily(Collection<Mammal> mammals) {}

@JsonTypeInfo(use = NAME, include = PROPERTY)
@JsonSubTypes({
    @JsonSubTypes.Type(value=Elephant.class, name = "Elephant"),
    @JsonSubTypes.Type(value=Whale.class, name = "Whale"),
})
public interface Mammal {}

public record Elephant(int hornLength, String continent) implements Mammal {}

public record Whale(double swimSpeed, String color) implements Mammal {}

Expected behavior

Records with polymorphic subtypes should contain all the information when received by the server. E.g.

2023-12-27 12:42:28,586 INFO  [org.acm.ser.MammalResource] (executor-thread-1) Received mammal family:
MammalFamily[mammals=[Whale[swimSpeed=30.0, color=white], Elephant[hornLength=10, continent=africa]]]

Actual behavior

Records with polymorphic subtypes are received by the server but they contain no data:

2023-12-27 12:47:43,323 INFO  [org.acm.ser.MammalResource] (executor-thread-1) Received mammal family:
MammalFamily[mammals=[Whale[swimSpeed=0.0, color=null], Elephant[hornLength=0, continent=null]]]

How to Reproduce?

1. Checkout reproducer
2. Run the JVM mode Quarkus server with mvn install -DskipTests && mvn quarkus:run -pl server
3. Build the native mode Quarkus client and run it with mvn install -DskipTests -Dnative -pl client && ./client/target/client-1.0.0-SNAPSHOT-runner
4. When the server receives the records from the client, they contain empty information:

2023-12-27 12:47:43,323 INFO  [org.acm.ser.MammalResource] (executor-thread-1) Received mammal family:
MammalFamily[mammals=[Whale[swimSpeed=0.0, color=null], Elephant[hornLength=0, continent=null]]]

In contrast, if the client is running in JVM mode, it all works as expected:

1. Checkout reproducer
2. Run the JVM mode Quarkus server with mvn install -DskipTests && mvn quarkus:run -pl server
3. Run the Quarkus client in JVM mode with mvn quarkus:run -pl server -pl client
4. The server receives the records from the client with the expected information:

2023-12-27 12:41:29,965 INFO  [org.acm.ser.MammalResource] (executor-thread-1) Received mammal family:
MammalFamily[mammals=[Whale[swimSpeed=30.0, color=white], Elephant[hornLength=10, continent=africa]]]

Additional information

Avoiding polymorphism can be a temporary workaround if the application supports it.
