[JAVA] JAX-RS Server InvalidDefinitionException: Cannot construct instance by using oneOf

Description

I have the following swagger.yaml that uses the oneOf keyword and I used the latest Swagger codegen tools (3.0.22) to create a server stub for JAX-RS Jersey.

openapi: 3.0.0
info:
  version: 0.0.1
  title: Polymorphism example
  description: ''

paths:
 /animal:
    post:
      summary: Create a new animal   
      requestBody:
        required: true
        content:
          application/json:
            schema:
              $ref: '#/components/schemas/Animal'
              
      responses:
        '201':
          description: Created        

components:
  schemas:
  
    Animal:
      properties:
        name: 
          type: string
        props:  
          oneOf:
            - $ref: '#/components/schemas/Fish'
            - $ref: '#/components/schemas/Dog'
      
      
    Fish:
      type: object
      properties:
        depth:
          type: integer
          
    
    Dog:
      type: object
      properties:
        country:
          type: string      

I am trying to post the following example object:

{
   "name":"Foo",
   "props":{
      "country":"Bar"
   }
}

But this results in the following exception:

javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `io.swagger.model.OneOfAnimalProps` (no Creators, like default construct, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information

Swagger-codegen version

Swagger-codegen version: 3.0.22

Command line used for generation

CLI command: java -jar swagger-codegen-cli.jar generate -i openapi.yaml -l jaxrs-jersey -o jaxrs-jersey/

Steps to reproduce

1. download swagger codegen 3.0.22 and save the swagger.yaml to openapi.yaml
2. java -jar swagger-codegen-cli.jar generate -i openapi.yaml -l jaxrs-jersey -o jaxrs-jersey/
3. cd jaxrs-jersey/
4. mvn jetty:run
5. post the above example object via curl: curl -X POST "http://localhost:8080/animal" -H "accept: */*" -H "Content-Type: application/json" -d "{\"name\":\"foo\",\"props\":{\"country\":\"bar\"}}"

Start by reproducing the failure with openapi.yaml, Swagger Codegen 3.0.22, the jaxrs-jersey generator, and the Maven Jetty run described in the issue. Inspect the generated Animal model and OneOfAnimalProps path shown in the Jackson stack trace. Done means the example POST payload is accepted by the generated JAX-RS Jersey server without InvalidDefinitionException.
