[BUG] [jaxrs-spec] Invalid return type for responses of type array

[bligny]

The following OpenApi response:

responses:

  AssignmentList:   
    schema:
      type: array     
      xml:
        name: assignments
        namespace: 'http://...'
        wrapped: true
      items:
        $ref: '#/definitions/TourAssignment'

is generating the following JAXRS-interface:

@Path(...)
@Produces(...)
@ApiOperation(...)
@ApiResponses(value = { 
    @ApiResponse(..., response=TourAssignment.class, responseContainer="List")
    })
List<TourAssignment> myWebService(); 

Please note the return type of the web service: List<TourAssignment>
I was rather expecting a separate "AssignmentList" java class.

This is working very fine for json response:

[
    {
        "agentID": "bligny",
        "assignmentDate": "2019-02-26"
    }
]

but in case of xml, the produced response is:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<collection xmlns:ns2="http://...">
    <ns2:assignment>
        <ns2:agentID>bligny</ns2:agentID>
        <ns2:assignmentDate>2019-02-26</ns2:assignmentDate>
    </ns2:assignment>
</collection>

This is in contradiction

• with the specs which states that the root element should be named "assignments"
• with the sample response generated by swagger-ui

Environment:

• openapi-generator-maven-plugin
• version: 3.3.4
• generatorName: jaxrs-spec
• jdk1.8.0_191
