WebClient.post().sendJson(Entity) throws EncodeException for PanacheBaseEntity

[willr3]

Describe the bug
I have a Hibernate @Entity which extends PanacheEntityBase with String, Integer, Boolean member variables and I want to send it as the json body in a vert.x WebClient. When I call webClient.post(...).sendJson(entity) I see:

io.vertx.core.json.EncodeException: Failed to encode as JSON: interface javax.enterprise.context.RequestScoped (through reference chain: io.hyperfoil.tools.repo.entity.json.Hook["persistent"])

Expected behavior
I would expect to be able to use the json encoding that gets used when I return the Entity from a method with @GET annotations

Actual behavior
The method throws an exception and doesn't send the post request

To Reproduce
Steps to reproduce the behavior:

1. Create an @Entity that extends PanacheBaseEntity
2. Create a Webclient and try to post the entity sendJson

Configuration

# Add your application.properties here, if applicable.

Additional context
I am able to send the Entity if I use sendBuffer(Buffer.buffer(JsonbBuilder.create().toJson(entity)))
(Add any other context about the problem here.)

This uses a different serialiser to the default jsonb used by RESTEasy, but it should still serialise entities properly.

This uses a different serialiser to the default jsonb used by RESTEasy, but it should still serialise entities properly.

I think it is not working because of the use of jackson within vertx. All the following issues:

• Kotlin data class not work without annotation #6041
• RESTEASY008200: JSON Binding deserialization error: No default constructor #5906
• Quarkus ignores mapped jackson annotations of 3rd party libraries #5969

are similar: quarkus cannot handle the propagation of the dedicated serialiser (either Json-B or Jackson) to its RS-component (e.g. RestEasy or Jersey). It always uses the host serializer even if other dependencies or extensions want to make use of another serializer as defined in its code. Quarkus ignores that. This leads to wrong (un)marshallings or unexpected error logs.

Is this still an issue?
